I'll second that, though I was unable to attend this year.
WOS maintains a really relaxed atmosphere - the room rates remain reasonable, it's not as hot, and the volunteers are a world class bunch who bust their hump to make the event, well, world class.
Two years ago, they welcomed the Healey team which brought some Brit car fans to the salt who would probably never have experienced it. This year, they made their event available to the T-2011 team from Granite Falls High School. You've got the 130 and 150 clubs, you've got the VW thing going on - they've found some unique angles to keep it fun and interesting without making it crazy.
Yes, as we found in '09 and this year, the weather is less likely to cooperate than in August, but they work around it - by WORKING around it.
To the volunteers
All the salt, without the hypertension.
