Too rich for my camping... I do alot of camping off-the grid in the Natl Forest areas close by here... Price is voluntary for $5 a day placed in a drop box... No paperwork included...
The camp sites along the Skyline Drive here in Virginia are $15-$20 a night and if you hold a senior pass you can get 50% off that including no fee for entering the Skyline Drive...
Typical Loft Mtn Tent camp site

There is also a heated central bath room building usually supporting two camping roads... Water is available from an outside spigot at the bath room facility
