Pine Barrens is the place to start but DON'T go there alone, There is someting like 500 miles of hiking/orv trails, some are restricted but marked and try to have a GPS, the "trails" (most of which are actually roads) show up on GPS. I've only been a couple times but I am completely stock. There are plenty of places to get swamped and stuck but most have go-arounds also.
BTW cell service is horrible so a CB helps
