>>2699805what about Vernooy Kill State Forest. right near catskills, would be a good place to dispersed camp. technically you're supposed to get "at least 150 feet away from the nearest road, trail, or body of water. Camping for more than three nights or in groups of ten or more requires a permit from a Forest Ranger."
if a trailhead allows overnight parking you can park there and march in a bit until you find somewhere quiet and out of sight. otherwise if your vehicle can handle driving around two-track roads, then just wander around during the day looking for sites or off shoot roads that other people have already broken in a bit. or find your own site. dont underestimate how quickly your tires can sink into mud, careful if it just rained. if you do get stuck dont panic just figure out how to get a tow truck. its expensive and sucks but not the end of the world
