The only NSRA events I've attended to date are OK City (not this year) and Springfield, MO (not going to make this year), but comparing the various Good Guy's venues with those two the only difference I see is the number of cars and the amount of shade. One of my favorite venues is Good Guys in Des Moines, Iowa around July 4th. Their fairgrounds is very old, set in the natural hills with lots of trees around very similar to Pleasanton, CA which is a fantastic venue, too. Springfield, MO is similar, but Des Moines is better. Westworld in AZ sucks to me - flat with miles of asphalt, and hot as Hades. Can't speak to any of the venues farther east.
