This is the type of situation that really makes it difficult for honest sportsmen. We have 180 acres in NE Oklahomathat has a lot of deer on it, and it happens to us alot b/c of an old highway the runs by the west edge of our property. Here it is shoot them off of the road and then come back later at night to get it. This is why I am finding it more difficult to head up to S. Dakota to bird hunt. The owners are having to charge people for land access because they can't trust anyone. I get it. I think I would be the same way. I think the best way to stop it would be to call the law or game warden, let them get their kill, and then have the law arrest them for illegal harvesting. They would lose everything. In Kansas if you get caught with an animal you took off of someones property without permission, they take your gun and your vehicle, you get a huge fine, and you get the pleasure of calling your spouse and telling her you were stupid and lost everything.
