There are a few options for black bear in Pa. Personally, I hunt Lycoming county every year. We have had a camp there for about 100 years and Lycoming harvested more bear than any other county last year. You could also look into pike county. The had 2 of the largest bear taken last year (roughly 800 lbs each). Either way it's going to be pretty tough with a bow because baiting is illegal in our state. Take into consideration the fact that only 10% of all bear hunters are successfull, and that's with rifle.
