If you guys are wanting a challenging park check out Adventure Offroad park in south Pittsburgh. It's owned by Tom of toms 4x4 and it's a nicely organized place. Huge grassy camping area with obstacle course when you enter the park. From the rear ya enter the trails which there is plenty of them. They are all numbered and color coded for difficulty. I rode there about a month n a half ago and it's one of the funnest places I've ever been. It's up there with tellico. I'm gonna try to make a trip up in 2 weeks to camp and ride. The easy to med trails are ok with min 33" tires and mild lift. The black/hard trails will require a more aggressive rig, lockers and and lots of susp travel.
