We considered moving to Blue Ridge from Atlanta a few years ago. I stopped at the only bike shop in town and was told than no one rides road bikes because there are no safe roads. Everyone rides mtn bikes.
The closest road riding in riding north on US129 from Vogel State Park to Blairsville. I've seen lots of folks riding along there.
I think there are a few other routes from Blairsville that folks ride, like Blairsville to Hiawassee or Young Harris and north from Blairsville toward Hayesville, NC.
Anyway, we decided not to make the move and ended up in west central FL. Now I ride the Withlacoochee, Suncoast, etc.
