HEre are some links. It was an old amusement park like Great Adventure's drive thru safari that was owned by Warner Bros. It closed years ago and now is just forest, ruins, and mountains. Where we ride you dont see too much of the park, but we do see some old buildings, fences, and roads.

And yes, there are some state lands up here, so it is at your own risk.
