If you go to the "thereabouts" around the Smokies, be sure to check out Deals Gap / Tail of the Dragon. Other "therabouts" could include The Grand Old Opre, or Dollywood.
If you are looking for something a little different and are history buff, I once did a tour of the major Civil War battlefields in the Pa, Va, W.Va, Md. areas. It was really cool seeing some of those places.
