On the raptor forum a bunch of the guys on the east coast travel to a bunch of spots up and down the east coast. But this place nick named Coal County - Treverton PA is suppose to be a 22k acre piece of land which consists of trails and hill climbs and etc. Pretty much anything for any rider. 100$ season pass goes on sale beginning of january, have to buy the pass in person i think at the location in potsville or something. I haven't personally been, but i am planning a trip for the spring. Here are some videos. If you youtube Tower City PA or Treverton PA or Coal County you'll see plenty of videos of this place. It has alot to show. The main guy who thought of coal county riders has been riding there for 5 years and he said he hasn't seen everything yet.
Its super nice up in trevorton i have a friend that has a cabin up there and we take the quads and dirtbikes up there all the time....great place to ride
