One good thing about PA as opposed to some other states is that the state makes the hunting laws and the PA Game Commission makes the regulations. No county or township or other municipality can make a law or ordinance that supersedes our Game laws. Not that some haven tried but the PGC is quick to point out to them that they have no authority do pass any law or ordinance regarding hunting and the PGC will send an officer to testify in the hunter's defense if they get pinched for some infraction of an invalid law. Federal laws that govern migratory bird hunting are the purview of the US Fish and Wildlife Service. However, a state may write laws or regulations that further restrict Federal laws and regulations, but they may not make laws that lessen the restrictions. I really feel bad for the hunters in states where counties, townships and other entities may write laws affecting hunting in their jurisdiction because it makes trying to stay within the law very difficult since there are so many different sets of laws.
