The Formula 1 world is bracing itself in anticipation of the unexpected when the travelling circus makes its next stop at Yeongam in Korea. The saga of the troubled construction of this new venue has been well documented. The latest setback came last week when newly published images appeared to show that a construction crane had toppled into the main grandstand.

After months of uncertainty, it now appears as though the Korean Grand Prix will go ahead, albeit in a facility that is not yet finished. The latest images seem to show that the circuit is finished, but the surroundings are far from perfect.

But as long as the circuit is there, a race can go ahead. The top layer of asphalt has only just gone down though, meaning that the F1 cars will have to cope with a very slippery circuit indeed next weekend. I can see it descending into farce, but it could be just the recipe for an exciting race weekend.

But what if there are still serious problems with the venue? It is unprecedented for F1 to head to a half-finished venue. You can think of Circuit de Catalunya, which held its first race in 1991 with its surroundings not looking in great nick — even though the circuit itself was perfectly usable.

The 1986 Hungarian Grand Prix also had a close shave. There are some incredible pictures of the warm-up races that clearly show the circuit still being worked on just weeks before the first Formula 1 grand prix was due to be held.

The problem is that the Korea International Circuit has not held anything in the way of proper racing yet. The circuit was “opened” on 4 September, with a demonstration run from Karun Chandhok in a Red Bull.

Clearly there was a lot of work still to be done. Multiple inspections have been cancelled. The FIA’s International Sporting Code (PDF), appendix O, article 3.4, states that a Formula 1 circuit must pass its final inspection at least 90 days before the race is due to go ahead. For other international events, the deadline is 60 days.

All of these deadlines have sailed past. An inspection due on 28 September was apparently cancelled by the FIA because there was nothing new to inspect.

Today, just ten days before F1 cars are due to go onto the track, the inspection is taking place. Now all indications are that the race will go ahead come what may. That seems to be because Bernie Ecclestone has decided it will do. To cancel the race now would be a disaster for everyone involved. It probably means cancelling next year’s race too, unless the FIA wants to overlook another of its rules.

I have no doubt that the FIA and Bernie Ecclestone know what they are doing. But surely all of those safety rules exist for a reason. Why have 90-day limits if, come crunch time, the money man decides a 10-day inspection will do the job?

What if something goes horribly wrong? I only ask because Bernie Ecclestone has gone on record during an interview with the BBC saying, “It’s quite dangerous what we’ve done, actually.”

It is true that this was Bernie Ecclestone’s way of giving the grand prix organisers the hurry-up in a public fashion. But to hear him describe “what we’ve done” as “dangerous” was surprising to me. It is a strong word that can be used against him and the FIA.

I know it says on the back of the ticket that motorsport is dangerous. But the FIA is supposed to ensure that dangers are eliminated wherever possible. It has apparently decided that this doesn’t matter in this instance. This is a precedent that surely shouldn’t be set.

What do viewers at home love about F1? It is great wheel-to-wheel racing? Lots of overtaking? Strategy calls? Or the venues? Looking at the polarised reactions to this past weekend’s Singapore Grand Prix got me wondering.

A few of the journalists were pretty effusive about the race. Will Buxton was particularly euphoric:

Epic race. One of the best of the season. Wow.

I saw that this drew a few hoots of derision, including from me! Because from the comments made by other fans watching at home was that… well… it was a bit dull really.

It wasn’t a stinker by any means. There was some good action and a fair few talking points. But large stretches of the race were rather processional. Hardly epic.

The epic race without the racing

Will Buxton justified his comments:

No sarcasm. Epic race. ALO VET lap trading, WEB early stop and brill drive, HAM / WEB moment, GLO driving arse off. KUB amazing.

There is some truth in what he says. While Webber and Kubica provided some entertainment, this was only because they were out of phase with the surrounding cars strategy-wise, so were not on an equal footing with the drivers they were battling with.

As for the battle at the front, the problem was that Alonso’s victory was never truly in doubt. He commanded the track all weekend, and always even looked like he might have a bit extra left in the tank too.

During the first phase of the race, Vettel drifted back to 3.5s behind Alonso. After the pitstops, the gap eventually grew to over 2s before slowly decreasing again. Vettel did get mighty close to the end of the race, but this was typical Alonso driving conservatively.

Renault engineers always talked about how conservative Alonso was as a driver. They never had to tell him to turn the engine down; he had already done it.

So it was in Singapore. Alonso had done just enough to establish himself as the certain winner of the Singapore Grand Prix and had the whole situation under control.

It may have looked good on the timing screens. I did indeed get excited when purple sectors were being set and Vettel started to decrease the gap. But the “lap battle” was partly down to the street circuit becoming cleaner and faster towards the end of the race.

I’m sure they were playing with each other, but neither looked to be pushing particularly hard. Alonso was always in control, and Vettel never looked interested in truly pressurising.

At the start of the race, Vettel had ceded the first corner, setting the tone for his race. It did not look like he was particularly interested in winning — a suspicion confirmed by Vettel’s comments that passing Alonso would have been too risky. And why bother? Alonso is the ultimate defensive driver, as his amazing battle with Michael Schumacher at the 2005 San Marino Grand Prix demonstrated.

The bottom line is that if you hold a race on a street circuit with one overtaking spot — two at a push — then the racing isn’t epic. There might be stuff surrounding the racing — strategy, crashes, pretty buildings… But not much overtaking.

Interesting, yes. Epic, no. The ingredients simply weren’t there.

Epic racing or epic facilities?

There is a trend for certain venues to be talked up a lot by the F1 circus, no matter how good the racing is. I particularly remember Valencia Street Circuit — which has served up three of the most turgid grands prix seen in the last decade — was universally praised by the teams as being a great venue for grand prix racing.

Scratch the surface of the headlines, though, and you see that they are not so interested in the racing itself. Ron Dennis said that the 2008 European Grand Prix at Valencia was so great that it made him “ashamed to be English”. But it left most others ashamed to be F1 fans, it was so bereft of racing.

Of course, Ron Dennis was thinking about the facilities. Facilities are apparently the only thing that matter in F1 these days. Never mind what the viewers at home make of the track. As long as the venue is equipped with a shiny silver throne for the McLaren chief to do his golden business in, who cares about the people at home?

Similarly, the journalists have clear favourite places to visit and places they can’t stand. China? Don’t talk to them about it. And spare a thought for poor, poor Magny-Cours. It was so awful — not because of the circuit, of course, but because it was in the middle of nowhere, as the journalists never missed the chance to remind us!

Meanwhile, Melbourne is always the “great place for a race” — is that code for a booze-up? And Singapore is now “epic”.

Never mind the fact that the Marina Bay Street Circuit is not great for overtaking. Never mind that the 2008 race needed a manufactured crash to pep it up, and that the 2009 race was voted the fourth worst of the season by F1 Fanatic readers.

TV coverage demonstrates skewed priorities

The scenario was not helped by some rather lacklustre television coverage from FOM this weekend. It looked to me like the director was more used to directing pop music videos than motorsport.

Coverage at night races is always dominated by shots of the lit-up buildings and the scenery surrounding the circuit. It feels more like the Singapore Grand Prix is more like an advert for Singapore than a motor race. Who was going to bed last weekend without seeing that flashing “Your Singapore” banner in their sleep?

When it comes to races like this, Bernie Ecclestone’s priorities are clear. Why else would the bland coverage of last year’s Abu Dhabi Grand Prix have won an FIA award for best coverage of the season? Much of the race action was missed. Anyone not paying full attention would have thought that the race was won by a hotel that looks like a giant flashing lady-toy, so fixated were the cameras on anything but the cars.

Those in the inner circle in F1 should remember that the fans at home are looking for epic racing — not epic Holywood movies, epic nightlife or epic superloos.

It has to be said that the writing was on the wall for the Bahrain Grand Prix before the teams even arrived there. And it’s not due to the refuelling ban. There are arguments for and against refuelling, but on balance I think banning refuelling is a good idea.

The legacy of refuelling

Some people had decided in advance that scrapping it was a bad idea, and have used the relatively pedestrian Bahrain Grand Prix as definitive evidence that they’re right. But one race is far too soon to judge. And as I pointed out in the previous article, there was actually more overtaking than normal.

It is no secret that F1 has a bit of an overtaking problem. The amount of overtaking has declined steadily throughout its history, and nose-dived in 1994 when refuelling was introduced in the modern era. In the intervening decade-and-a-half, the amount of overtaking has been relatively stable at this low level.

For me, the biggest legacy of refuelling has been to gift seven World Championships to a driver who isn’t particularly good at wheel-to-wheel racing, but transformed “overtaking into the pit lane” (i.e. gaining positions just by being in the pit lane at the right time) into the most important aspect of modern-day grand prix racing.

It is often argued that this “strategy” element adds an important dimension to the racing. The argument goes that what is lost in terms of on-track action is gained in terms of strategic intrigue.

This may have been true in the early days of refuelling, when strategists were still finding their feet with the new rules. But over time, it became clear what worked and what didn’t.

Armed with 15 years’ worth of data, teams had their strategies worked out by computers to the extent that there was one clear optimal strategy, and the race was won or lost on whether your first stop was made on lap 17 or made on lap 18. More often than not, after the first stop, it was clear how the rest of the race would play out, and the whole spectacle usually settled down.

The powers that be concocted increasingly contrived ways to re-inject a strategic element into the racing, but it stopped working. We reached the ridiculous situation where cars were qualifying on race fuel loads, which still did little to avoid the harsh reality that there is one optimal strategy.

How to re-introduce strategy while keeping purists happy

For me, there is far too much talk about “the show”. F1 is not a show. It is a sport. As far as I’m concerned, if you want to see a show, you should go to the pantomime. Todd on the latest Formula 1 Blog podcast said it best: “Jim Clark didn’t take part in a show. He took part in a race.”

Yet, with the obsession with making F1 more entertaining, the rules have constantly been tinkered with. Sometimes it works and sometimes it doesn’t, and the powers that be have to tread a fine line. They must make the sport more appealing to people who, truth be told, aren’t really interested in F1, while keeping the purists happy.

F1 is special because it is, at its core, about finding the fastest driver in the fastest car. Everything else is tinsel. Some of the new rules actively go against this attempt to find the fastest.

Look at the obsession with strategy. Look at attempts at mixing up the grid. The current tyre rules are among the most unpure in F1 today.

Forcing drivers to use two different types of compounds achieves nothing for anyone except Bridgestone. And I am yet to work out what is achieved by the new rule forcing drivers to start the race on the same tyres they qualified on. What does it prove? Do we tie one hand behind the back of footballers to “spice up the show” there? It is ridiculous.

Yet, all the talk is to introduce a mandatory two stops. That is certainly what Martin Whitmarsh implied on the BBC’s coverage last weekend. The idea sends a shiver down my spine. And quite how it is supposed to spice up the action is beyond me. Just now the optimal strategy appears to be a one-stop. Now they want to enforce a two-stop strategy? It’s difficult to see the scope for spiced-up strategy action here.

But I can think of a way of re-introducing the strategy element while keeping the purists happy: get rid of the mandatory tyre change. This would blow wide open the possibility of a no-stop strategy, thereby potentially reducing the predictability of the current situation. Sure, Bridgestone will be unhappy — but they are leaving the sport anyway so there is no point in making them happy.

Aerodynamics

The decline in overtaking pre-dates 1994. It has been clear for years that it is not as easy for F1 drivers in F1 cars to overtake as it perhaps should be. There are plenty of pet theories as to why this might be. The ones that get the most attention are the ones that are put forward by Bernie Ecclestone and the FIA, as they are the most powerful people in F1. But of course, they have their own agendas.

The FIA and Bernie Ecclestone have long blamed modern aerodynamics for the lack of overtaking. The received wisdom has become that aerodynamic grip is bad news if you want overtaking, and that the emphasis should be more on mechanical grip.

I was very interested to see James Allen write about what Frank Dernie thinks about this — that’s it’s a load of old cobblers. I have felt for a while that the argument that aerodynamics damage the racing does not hold water. On a Renault podcast a couple of years ago, Pat Symonds pointed out that the races that have the most overtaking, as everyone knows, are wet races. In the wet, aerodynamic grip is ramped up, and mechanical grip plummets.

When you think about it, it’s so right. It does amaze me that, in the face of so much hard evidence to the contrary, people still blame aerodynamics for the poor racing. I have come to the conclusion that many people’s views on the overtaking problem are shaped largely by fashion and spin rather than the evidence.

Speaking personally, I love seeing what sorts of devices teams come up with. We have all been fascinated by McLaren’s “F-duct” (even though it seems to have done them “F-all” good). Neutering these sorts of areas is the first step on the slippery slope towards spec chassis. And then it just wouldn’t be F1 any more.

I am not totally averse to restricting the cars though. Formula 1 is, after all, a formula — it always has been.

I am no engineer, but it strikes me that F1 cars are simply too fast to allow for much overtaking. In particular, the brakes on F1 cars are so good today that there is little opportunity for a driver to perform an outbraking manoeuvre. With such small braking zones, the scope just isn’t there in the same way it might have been in the past. Is somehow reducing the power of the brakes a viable option?

The points system

Bernie Ecclestone has also sought to blame the points system for the lack of overtaking, and the system has accordingly been tweaked. I personally think there is something in this. The points system rewards conservatism.

Think about instances where a driver attempting to overtake faces a 50-50 situation (or, more accurately, a ⅓-⅓-⅓ situation). By this I mean that there is a ⅓ chance that a clean pass will be made and a position will be gained, a ⅓ chance that an attempt will be made but will fail, and a ⅓ that the move will go wrong and end in a crash. (Obviously this is a major simplification of the real-life scenario, but I think this “50-50″ thought experiment still underlines an interesting point.)

Under last year’s scoring system, for a driver in second place trying to overtake the leader, this “⅓-⅓-⅓” situation would lead to an expected gain of… -2 points. Under the new points system, the expectation is -3⅔ (although as a percentage of the winner’s points haul, this is better). No wonder drivers can’t overtake. It’s not in their interests to even try unless they are practically left an open door.

This was the core reason why I was in fact, contrary to the fashion, in favour of Bernie’s proposed “medals” system. Then, attempting to gain a position would be unambiguously advantageous.

The circuits

However, I think there would be much more to be gained in ensuring that circuits are more challenging and provide more in the way of opportunities to overtake. Nothing is certain. After all, Suzuka is normally entertaining, but produced a bit of a stinker last year. Sometimes it just doesn’t happen.

But we all know that certain circuits, in general, produce better racing than others. I really do struggle to think of any grand prix held at Interlagos that was boring. But I know not to expect much action at, say, Valencia or Shanghai. Or Bahrain for that matter.

We know this because teams and drivers will often turn up a circuit and say, “there is only a certain place you can overtake, and it’s here”. Adrian Newey, Sam Michael and Martin Whitmarsh are all in agreement. As the Williams technical director said:

You’ve got to ask yourself, why do you go to a race such as Barcelona where no one overtakes, and then take exactly the same cars to Monza, Montreal or Hockenheim and you get lots of overtaking.

And the McLaren team principal said:

You only need to do simple statistical analysis and look at where the overtaking moves are If, say, we race on 18 circuits with 350 corners, then 90 per cent of overtaking moves in a year would happen at just 10 corners… The fact that overtaking is focused on such a small number of corners clearly demonstrates that it’s circuit-dependent.

Ferrari and Renault went to Valencia in 2008 proclaiming that they know from their simulators that there would be little in the way of overtaking. Ferrari even based a fundamental decision about their engine on this prediction. And they were right.

But Bernie will not entertain the suggestion that the circuits are to blame. This is because, unlike the effort made by drivers or the aerodynamics or the strategy, this is the area that he is responsible for. And he doesn’t want to take responsibility for it.

The effect of adding a new slow, narrow, bumpy, twisty section that looks as though it was almost designed to prevent overtaking was predicted before the race began. Quite why the organisers of the grand prix thought it would be a good idea is beyond me.

GP2 world feed commentator Will Buxton saw the writing on the wall, and was left exasperated by the negative effect this different circuit configuration had on the GP2 racing. He predicted a similar negative effect on F1, and it transpired that he was right.

What else is Bernie to blame for?

While I confess that it is a bit too easy to lay the blame on Bernie Ecclestone for the boring race in Bahrain, there is another core part of F1 that he is responsible for, which led to a dull spectacle being played out in our living rooms last Sunday. But that is what I will deal with in another article in the near future.

Allow me to explain. Despite all the jibes about Luca Badoer struggling, it occurred to me that he may now have another unusual record to add to his list.

Here is the official lap chart for this year’s Belgian Grand Prix, as published by the FIA. Do you spot anything unusual about it?

2009 Belgian Grand Prix lap chart

Despite the fact that he was last of the classified runners, Badoer was only 102.1 seconds behind the race winner, Kimi Räikkönen. “Only?”, I hear you say. But he was still on the lead lap. In fact, the lap chart reveals that there was no lapped traffic for the entire race.

I wonder if this is a first. There are a few things that lead me to believe this is the case. First of all, it is commonly believed that Formula 1 cars have never been as close in terms of performance. Surely the amazing speed of the Force India in Belgium is testament to the idea that there are no longer backmarkers in F1 like there used to be.

Luca Badoer, the slowest man in qualifying, was around 2.5 seconds off the quickest time. Although in F1-2009 style this invites derision, even five years ago this would have been a creditable performance. Read a grid from the 1990s, and it is routine to see cars a dozen seconds or more off the pace.

Furthermore, Spa-Francorchamps also has the longest laptime of any circuit currently in use in F1, which in itself makes it less likely that cars will be lapped during the race. I have checked some previous Belgian Grands Prix to check, but all have had lapped cars, apart from this year’s. For this reason, it is also possible that some races at longer circuits used in history (notably the Nordschleife) may not have seen any lapped traffic, but with more reliability problems and poorer driving standards back then, I wouldn’t count on it.

(Update: I have checked all Formula 1 Grands Prix to have been held at the Nordschleife, and each race had classified runners not on the lead lap according to Wikipedia.)

Against that argument is the fact that since 2007, lapped cars have been able to join the lead lap behind the Safety Car. This makes it much less likely that there will be lapped cars at the end of the race — but there will still have been lapped cars during the race.

I asked on Twitter if this was the first time none of the classified runners had been lapped. Amazingly, Alianora La Canta set to work and used her awesome research skills to find out that the last time all the classified runners finished on the lead lap was at the 2007 Canadian Grand Prix.

However, this was one instance where a Safety Car allowed lapped cars to join the lead lap. The official lap chart (PDF) reminds us that there was indeed lapped traffic during the race.

So it looks like I may be right in my hunch that Badoer is the only person ever to finish in last place, yet not have been lapped during the race. So does anyone know if Badoer’s achievement truly is a first? I would love to know.

As ever, Keith at F1 Fanatic provides us with a list of interesting facts about the race. I wonder if Badoer’s fast last place is one to add to that list.

The final part of the factory tour was the chance to see the simulator. It is an impressive piece of kit. The driver sits in a cockpit, surrounded by a massive screen that curves round to take up his entire field of vision.

Little wonder it has been known to induce sickness. Drivers are advised that they may want to close eyes if they spin in order to avoid reacquainting themselves with their lunch. Apparently drivers have been known to be sick all over the place while driving the simulator. Come to think of it, I’m slightly suspicious because I remember that the cleaner was leaving the room just as we were entering it. We were told, though, that Kazuki Nakajima is amazing in the simulator and can spend all day in it with no ill effects.

The circuit models are said to be very accurate indeed, albeit some more accurate than others. For instance, someone else has exclusive rights to the best map of the Nürburgring. The maps are constructed using lasers. A van drives slowly around the circuit emitting laser beams at multiple angles, creating a map of millions of dots. This means that every bump on the circuit is accounted for.

An aerial image of the circuit is then overlaid on top of these dots to create the environment. But if you look at the circuit, some of the landmarks are not very accurately reproduced. In fact, some of it looks like bad virtual reality graphics. The idea is to reduce any confusion that might be caused by too many cues. If they don’t think something will give a driver an accurate cue, they won’t implement it.

Some teams have more sophisticated simulators. In some simulators the car will be on a moving platform to give the impression of movement — something clearly lacking from the still Williams cockpit. It is said that some simulators even have belts that tighten up to give you some impression of g-forces. Williams shun such devices, which they regard as off-putting.

I have to confess that I have been slightly sceptical about the Williams simulator in the past. McLaren’s is said to be amazing, but it is jealously kept under wraps from outsiders. Williams have no such qualms however. It is the only simulator that I have seen on television. See, for instance, this ITV video with Mark Blundell and this BBC video.

We were lucky enough to be in the room when occasional Williams tester Daniel Clos was driving it. He was there to acquaint himself with the Hungaroring in preparation for the GP2 races which were being held just a few days later. I have to say he didn’t look very good while we were there, and he even spun at one point. But those must have been his very first laps round the circuit and of course I am in no position to pass comment. In the real thing, he finished 11th in both races.

It is presumably a service that Williams are happy to offer young drivers in the hope of developing them into a Formula 1 star of the future. Whether Daniel Clos is one remains to be seen. But surely on his way to F1 stardom is another Williams tester, Nico Hülkenberg. Simulator Engineer Jeff Calam is adamant that the simulator is a worthwhile piece of equipment to invest in, pointing at Hülkenberg’s highly impressive GP2 results at circuits he hasn’t driven at before. This fact puts to bed my doubts about the quality of the Williams simulator.

Once the factory tour was over, we had a Q&A with Sam Michael. He was largely very open in his responses, and came across very well to me. I was impressed that he took the time out of his schedule to talk to a bunch of bloggers. You can hear audio of the Q&A session over at Brits on Pole once again.

After that, we went for a tour of the fabulous Williams museum. Here, we were expertly guided by Scott Garrett from Synergy, the company that arranged our visit on behalf of Philips. Although he now works for Synergy, he was previously Head of Marketing at Williams and now has links with a number of F1 teams. This makes him a highly knowledgeable speaker on Formula 1, and Williams in particular. It was a real pleasure to have this sort of insight.

For obvious reasons, photography was strictly forbidden in the factory, but we were free to take as many photographs as we wanted in the museum. And boy did we take the opportunity!

Early Williams cars The museum is impressive, with a range of cars from the full history of the Williams team’s existence. The first car you see is Alan Jones’s FW06 with its Ford Cosworth engine peering out the back. Cars are displayed, more or less a car for every year, right up to 2007′s FW29 — the very car that the competition winner will be driving.

All-in-all, the museum contains over forty cars. We are told that Frank Williams is a hoarder. The team still owns 106 chassis, while it only makes around six per year. Most of these cars are well looked after and can theoretically still be driven. The main exception is the Honda-powered cars, because they asked for the engines back!

For the most part, the cars are laid out in chronological order, and as you make your way through the museum videos are played telling us about Williams during the period of the cars in the vicinity. The relevant cars are lit up while the video is playing.

Unfortunately, this means that they are plunged into darkness once the video is finished, and you are supposed to move along to the next section. It is a pretty clever device to get us to keep moving and get rid of us quickly, but quite annoying for those of us who would have liked to have done it at our own pace. One person sarcastically remarked under his breath, “you have a lot of great cars, then put them in the dark.” It is for this reason that the lighting is not very good in some of the photographs.

Despite the chronological layout of the museum, there is still a fairly clear centrepiece. Two cars in particular are displayed on a higher plinth — the FW18 and the FW19, the team’s latest two championship-winning cars from 1996 and 1997 driven by Damon Hill and Jacques Villeneuve.

FW19 and FW18

A great moment of F1 geekery occurred when Mr Garrett pointed out that the FW19 on display is the actual car which Michael Schumacher famously crashed into at Jerez in 1997. Everyone went “oooh” and inquisitively gathered to look at this particularly historic Williams F1 car. The damage is still evident. I had heard that Patrick Head liked the car to be displayed with the tyre mark still there, but it has since been restored and now just looks like a couple of holes have been punched in the corner of the sidepod.

“We never got on very well with Michael Schumacher,” Scott Garrett noted, just in case we didn’t get the clue. This prompted a cheeky question from someone else, “How did you get on with Ralf?”

There is a notable omission. The most distinctive F1 car in the team’s history, the FW26 with the “walrus nose” is nowhere to be seen. It is perhaps not the team’s proudest design.

One unusual design does proudly feature though. Williams were never able to race with their FW08B six-wheeler. It was banned by the FIA before the season started over fears that it would be too dominant.

FW08B - the unraced Williams six-wheeler

Keke Rosberg's record-breaking FW10 Go up the stairs, and you will see two cars that are clearly very special to the team. One is Ayrton Senna’s test car from 1994. The other is the record-breaking FW10, in which Keke Rosberg was the first person ever to set a lap at a speed of 160mph in 1985. The record was set at Silverstone and remarkably stayed in place until 2002!

All-in-all, it was an absolutely fantastic day. Although Williams are not among my favourite teams, they have got to be admired for being so accommodating to us. If you ever get the chance to attend such an event, I would highly recommend it. A massive thank you to those who organised it and invited me.

Below is the full slideshow of photographs from my visit to Williams.
