I have contacted the Nolinchucky River Campground in Erwin, TN. who said they could provide a shuttle with my car. They would drive me in my car to the trailhead and then drive back with my car & keys to park it at the campground to await my arrival back at the campground a few days later. I'm a bit nervous about this arrangement. Are there some safeguards to put in place to avoid someone running off with my car? Or should I try to contact another shuttler? I chose this campground since it runs right by the AT & is so convenient.
