http://www.pgc.state.pa.us/portal/se...unity/pgc/9106 click on seasons and bag limits or the hunting digest and find bear season. There are several starting in Sept in a few management units for archery, then a muzleloader season and a regular firearms season with some extensions. If it was only one season I would have just posted it, I got it from my digest.
