That is the problem where a county or municipality can pass it's own laws regarding hunting. It creates a lot of confusion. One thing that PA did right was to give full authority over wildlife, hunting and hunting methods to it's game agency. No other government entity can pass valid laws or ordinances relating to hunting. The Game and wildlife code supersedes any laws passed by municipal entities with regards to hunting. It has been tried and failed because of the way the Game and Wildlife Code is written. We have 67 counties and each of those counties have townships and towns and villages and cities. To allow all those entities to pass their own ordinances relating to hunting would be a giant goat rope and a nightmare. The Capital city of Harrisburg not all that long ago had a mayor who didn't want hunters on the Susquehanna river hunting waterfowl because some of the river is within the city limits. He would sent the police out on the river to harass waterfowlers and tell them they were hunting within the city limits and discharging a firearm inside the city limits was illegal. The Game Commission received complaints from hunters and contacted the Mayor's office and told him the city had no jurisdiction over hunting or hunters and so long as they were 150 yards off shore they were perfectly legal. Finally, after another complaint the city attorney was contacted and told the next complaint of harassment by hunters who were being harassed while legally hunting on the river would result in the the PGC filing "hunter harassment charges against the police officers who were interfering with hunters and support any hunter who sued the Mayor and the city for harassment by testifying in the civil court for the hunters. finally, after several years of dealing with this nonsense, the harassment ended. I can't imaging living and hunting in a state that had a mish mash of laws passed by multiple government entities controlling hunting and trying to memorize or know all of them. PA may not allow semi auto firearms for hunting, but they are ahead of the curve on this issue.
