I'd say Knoxville for being a racy surface although I'm not much of a sprint car fan. So I guess I'd have to go with Lucas Oil Speedway in Wheatland, MO. Lots of variety with the different classes, the drag boat course and the off road course. It's off the beaten path but that sure makes it easy to get in and out of. The facility and track amenities are probably some of the best. Lodging close by can be a challenge unless you plan way ahead or have an RV.
