Well, my wife and I decided to make the trip for the first time and enjoyed it a lot. I think our age is twice that of the average attendee and the show attracts a great many performance enthusiasts, but we found plenty to see and met a lot of nice people with incredible skills. The Sunday cruise was a blast and is quite a sight. We did the "course" in our JSW TDI (following another TDI) and really enjoyed the spirited mountain driving.
There were a lot of Vendors there and VW brought in a fancy 18-Wheeler with give-away stuff for anyone who showed their VW key.
I'm not sure how many VWs arrived, but it was at least 1000 and some estimates we heard were nearly twice that! The hotels were also packed with VWs. Our JSW was carefully backed in along with dozens of other models, interupted only by a lone Honda Accord innocently parked by someone who had stopped for a night's rest!
