I made passes over the Dragon in both of my Vettes. I fun road to drive, but you have to very careful. The police patrol it very aggressive at times, big trucks travel it and maniacs on motorcycles tear it up. We have a few good roads in North Georgia that are lots of fun also.
You will love running the Tail of the Dragon, but visit
