LIke Hammer said, the venue at dayton this year was really nice. Have to figure most of the area construction will be completed next year, so even smoother sailing.
On a different note, although Dayton is great, I would not mind seeing a more central US location...like Kansas City or something. It might allow more Western US participation.
I'm in N. Texas, and it was a solid 16 hour drive, with trailer, to Dayton. Not bad, but it allows us to see why little/no AZ/CA/Nevada/WASH/etc... cars make the trip.
Just a thought.
