Without stealthing, where can you camp on the up and up for free? Are there long sections of a route that are like that?
Close to me, there is Dawson Forest. There are no camp sites per se. You just camp where you want to and pay no fee (there's a parking fee if you show up in a vehicle but that's inapplicable for bicycles).
There's also Bankhead Forest, where I've camped in the neighboring state of Alabama. They have free dispersed camping and I stayed there on a tour last fall.
But in each of these cases they are isolated stops. Not a situation where you ride day after day camping for free.
I know there are hiker/biker campgrounds on the towpath and allegeny passage. Are there other places where you might ride day after day camping for free? Are they specific campsites? How far apart are they?
