The Syracuse Nationals can get hot too, but it wasn't as hot as Carlisle this year. More blacktop in Syracuse, but there's a couple buildings that have AC. The "Expo Center" building is big, has some custom cars and is almost cold, so you can cool off in there. There's a restaurant on the grounds that has AC also. I was with the local AACA club so I got to park with their display in one of the buildings. No AC in that one, but still out of the sun.
Carlisle was brutally hot this year.... Yea, about 2 zillion degrees is right.
