We have one 30A spot with water and sewer, and several 15A with water only. Plus about a hundred acres with no hook ups. Horses, dogs and cats abound. We don't charge, but will accept donations of whatever you feel the spot is worth and you can afford. The website won't let me put $0 for a charge.
Boat ramp into Watts Bar Lake about 2 miles, convenience store with gas and diesel 1 mile, swimming hole 3 miles, lake swimming just down a steep hill, and waterfalls, mountains, hiking trails and professional live theater all within an hour. Walk-up propane is 7 miles away, and it's about 12 miles to drive-up propane.
