The parks suggested by tnjimbob and TLG look great... One is in the Great SMokies, which may be a little cooler, and the other is nearer to Nashville - which may be more centralized as a location. But - the drive time difference is 2-1/2 to 3 hours in an east/west
If there are more suggestions - please post them. Hopefully we can distill these into a pro and con discussion - then a poll to see what the majority would like to do?
