I have an old road bike with a broken derailleur that I've been thinking of converting to a one-speed bike for the Geenbrier River Trail (I put the widest tires that would fit on it, and I think it would be well suited to that trail - at least the southern part of it where I walk my dog). Maybe I'll start riding longer sections with a view to locating camping spots. I have just talked with Mike Smith, the ranger at Droop Mt. Park (Civil War battle site), because he used to take care of the river Trail too. He says there are developed campsites about every 5 miles along the trail, many of them with pumps and some with toilets. (Toilets are spaced about every 13 miles, he says.) Camping is allowed anywhere along the trail, not just in developed sites. The width of the park varies from 50' to 200' or so. Stealth camping would be easy in some areas, but difficult in others. If I get around to biking it I'll locate some good trees to hang from.
