try talking to them first. Politely explain your safety concerns and depending on how that interaction goes you’ll know where you stand. while you see their blind/camp to close to your property line they may see yours as encroaching on thiers. i would suggest that you would both move away from the property line away from each other. just my thoughts.
I have similar thoughts.
I would certainly have a conversation and share your safety concerns and to prepare for this conversation, I would research:
1. Does PA have any laws regarding the distance a hunter must be from a dwelling/building to legally discharge a firearm? Many states do. If the blind is closer than the law allows, I would politely point this out.
2. Does PA have any laws that say a hunter cannot shoot such that a projectile will cross a property line? Rare, but I believe some states back east do have laws like this for deer hunting.
However…Now I do have another point here. You mention several times about the location of his house:
the difference is our house is the only house in the area. he just bought 100 acres and his house is no where near where he set up. so our home is the only one in sight. just weird to me i guess. that is a good point about them thinking we are to close to theirs
Just understand that the location of his dwelling doesn’t matter. The other owner is entitled to the full use of his property so long as he is doing so within the law. It’s his property, so you can certainly talk to him about safety concerns, but as long as his activities are legal, how he uses his property is his business. It was nice for you that the previous owner did not have a blind near the property line, but that doesn’t mean that just because his house is elsewhere, there’s some obligation on his part not to hunt near you and doing so doesn’t, IMO, make him a bad neighbor. He’s simply using his property differently than the old owner.
