Nothing personal, but someone’s right to hunt ends where my property line begins.
If I wish to allow someone to hunt on my property, they will. If I don’t wish them to hunt on my property, they won’t.
Site history, tradition, or anything else you want. Property rights trumps it.
To be fair, if this particular hunting right has existed since before you bought your property--and probably since the land grant was first made conferring private property rights--it's almost as though you've never really had absolute property rights to keep hunters off your land. It's like you bought it knowing there was an easement allowing others some use, so you can't really cite property rights as a reason to prevent that use.
Nonetheless, it does seem like a pretty silly law.
