There are quite a few places that only allow shotguns. Sometimes it is states and sometimes just parts of states. I hunted a lot of military bases before I retired and they usually only allow shotguns or muzzleloaders. I killed a lot of deer with a 12 gauge pump.
Like RR, I'm glad you love PA. I've hunted there twice myself but I like other states more for hunting but I still go to Lancaster every year on my way back from seeing the in laws in NH to buy some Amish specialties.
