RE: Southwestern PA
I have a friend who lives in Bridgeville, he hunts up near Franklin as he has a camp up there, but that is about 1 hour away (or slightly more). Not sure, but I thought he had mentioned Waynesburg ?? How far is that from you ? No public land, but some door to door might get you somewhere. If not offer up (if willing) to lease some ground for yourself. If you strick out there check to see if your county has a GIS Map, this will give you some names of landowners, some of which may be timber companies...gives you a start on who to contact.
Good Luck
