i posted that same question a few weeks ago bud. The only real good answer i got was the Pine Barrens in Jersey. I live in Warminster PA, not too far from u and its about 1hour from me. I have yet to go check it out though. Try a google search, there is a lot of info on the Barrens, but most is irrelevant. It a park with a bunch of dirt roads basically. If u ever want to go check it out let me know. Im as curious as u are, but i havent had time to go yet.
