@rainman and
@Dr.D should chime in, as well...
I'm not sure how long you have, so I'll try to stay in the general TOD area.... In no certain order, except for #1
1) The Snake- this is IMO the finest stretch of blacktop I've ever come across. As if built custom for us... it's between Mountain City, TN and Bristol on Hwy 421.
2) The Rattler from (or to) Hot Springs, NC Hwy 209
3) The Devil's Triangle- starts at Brushy Mountain State Prison in Petros, TN.
4) Aces and Eights -
@rainman can give you info on this one.
5) So many more- let us know where all you plan to be and we can suggest more. I have several just miles from my house. It's Disneyland around here.
Be on the lookout for a physical map (Wild Rides) that has tons of routes (free). I would think that the shop at the start of TOD has them, but they're widely available in motorcycle related places and even restaurants in the entire region.
