We are planning a road trip mid to late May 2012 from western NC to Anderson (near Houston) Texas. After visiting part of the Blue Ridge Parkway we intend to start our journey in the Great Smokey Mountains and I would welcome advise on the best route. We are looking for the most scenic route (not the shortest perhaps) and would like to avoid the big towns. We are English (no children) and never visited the area before. We intend to hire a car and allow four or five days for the journey.
