Looking to visit the fair state of Tennessee for our first time. We are looking for some scenic routes to take for RV (trailer 27' Lance 4 season) and must-see sites if anyone knows of any. We are leaving from Nebraska, so we will have a few states to pass through if any other must-see sites come up. And must-see camp grounds. Some are beautiful!! We have been west of NE but not too much east. Any recommendations will be appreciated. Thanks so much.
