I would go here and check out all of the maps of area roads and places to explore. http://www.tailofthedragonmaps.com/
There is a lot of good info there. I would also go here and check out these videos so you will be forewarned of the insanity of 18 wheelers at Deals Gap and any other twisty two lane hwy in the area. http://www.youtube.com/watch?v=6haNzNzWG-0
I have been run off of the road by an 18 wheeler on Hwy 28 going to Franklin, NC. I was on a motorcycle at the time and there was a smooth dry grass shoulder area for run off, thank god. I was able to keep the bike up and not crash, but the truck was 100% in my lane in a series of tight turns, just like in some of the videos. The truck didn't even slow down, just another innocent passerby run off the road, no big deal!
