Join a club, then you'll have access to some of the afformentioned private land, and people to wheel with/ wrench with. I don't know where you are located but the two closest clubs to that area are Hudson Valley 4 Wheelers, and my club located out of the Albany to points north area, Adirondack Jeeps. Get in touch with HV4W, it sounds like they're closer to you. I haven't talked to those guys in a few years now but when I did Andy was the guy in charge, and he had a white TJ on D44's and 35's. Great guys, I've wheeled with them before and they've been doing it for a long time, they know their stuff and come prepared (including power tools and inverters for trail emergencies)!
