Ok... Chattanooga looks good but if you want to run the dragon, believe me... Coming from chattanooga hitting the dragon and then driving back is a pita! That road mentally drains me every time I run it and I grew up right at the base of it. Fontana Village is right there adjacent to the dragon on another amazing road named the hellbender. I will post a link here in a second but they have great facilities that accommodate a large variety of wallet sizes if you know what I mean. The last meet I went to there, they allowed us to pull all the cars onto the baseball field for photos and they turned out great!
