Yeah, my luck in PA has been pretty limited...

Besides having to reserve and stay at the park sites, last spring trip up there I remember getting pulled over by park police or whoever resides over it and getting an earful cause we didn't have some special use permit or something. They don't make it super clear on the websites that a group larger than like 3 trucks (don't remember the exact number) had to have said permit. Kinda soured me on exploring PA any further, which is a shame, cause it's beautiful up there.

@jcaino Your route looks interesting, I've run a bunch of the stuff around Harrisonburg, I could point you to some more roads through there if you want to get off pavement more, feel free to PM me.
