I'm not a PA boy, but a neighbor in Maryland and also think the out of date, no Sunday hunting blue laws are outdated and in need of change.
If my information is correct there are only 7 states left that have such laws and they are all here in the east. Maryland is getting a little better and we now have 5 Sunday hunting days during deer season, but only on private property. Is it what we want? No, but it is progress. Last year we only had 3 so it's a step in the right direction.
Not that you asked for advice, but here it is. If you don't like the law...try to change it. Talk to your representatives and get involved. Let them know it's important to you and you are a voter.
Best of luck.
