I know! Right adjacent to prince william fotest park is the chopowamsick back country area. No one is ever there, and there is a campsite right at the edge of the lake. There were bear tracks when I was last there so just take precaution.
It is also a bit tricky to get back therebecause the entrance to the place is next to a military compound but park before you pass the unauthorized vehicles shall not pass sign.
