I know this post is old, but I am 15mins out of Bensalem in Yardley. My dad and I go riding up at rausch creek Pennsylvania. It has over 8,000 acres and you cand do what ever you want. (no alcohol and drugs of corse). There are no restrictions as to what you can do. Te property is on old mine reserves so there are a few cool mines hafts to go look at. There are also plenty of hill climbs and tech trails. I love this place. look at my youtube for some videos.
