Ask the owner to write down on paper that you have the ONLY Permission to be hunting her land, and then attach a plat map of her land. If you see someone hunting on the land, call the Sheriff. Show them your paper work( have a phone number available so they can call the land owner from a cell phone) and ask the Sheriff to either escort these trespassers off, or arrest them. That is the Only way this stops.
I ran into this with a good friend who took a job taking care of some few acres for a Professor, who wanted to have a garden there, and grow fruit trees in a meadow. The ground hogs, birds, and deer were eating everything in the garden, and the deer were eating the bark off the fruit trees and killing them. The owner didn't "believe in hunting", but after being told by the Ill. Dept. of Conservation officer that he could not obtain a nuisance permit to kill the offending deer unless he first allowed hunters on the land in hope that they would kill enough of the deer that the amount of destruction to his trees would be reduced. The first year we were hunting there, I Helped Don put up NEW " No Hunting" and NO trespassing " signs both at the entrance to the property, and then along the boundary fence, and at any trail crossing onto the land. When the season started, sure enough, we found locals hunting on the farm without permission. They tried to buffalo us by saying they had permission and had hunted the ground for years. Don kicked them off. They came back, later, drunk, and armed with shotguns, and threatened to Kill Don for throwing them off the ground. I was standing to their right, apparently unseen at first, and I had my revolver in hand behind my back, picking my spot on the Loudmouth's chest where My shot would take both his hear and spinal cord out. A revolver against two shotguns is Not a fair fight, and they drafted an Archer with them, who stood closest to me with a broadhead nocked on his bowstring. The cursing and threats carried on for a couple of minutes, and then they let Don speak. He told them who he worked for, how long the professor had owned the farm, that it was posted when he first came down to the property to mow the grass the prior spring, and that the new signs were posted prominently- including right next to where the two shotgun guys had parked their truck! Since the signs had blaze orange letters on a black background its Impossible that these two men did not see the sign when they pulled in. They also parked on the neighbor's side of the property line, and not on the farm, where the tire tracks indicated that they had parked on past visits. ( Its useless to try to lie to Trackers!)
Once Don explained his job, they started in threatening him again, and that is when the loudmouth in the middle looked over and saw me, with my arm behind my back, not saying anything, but leaning forward in an aggressive posture. He did a double take, then stopped threatening and cussing, and dropped his voice down. The other shotgun shooter next to him on the left, looked over at him to find out why the sudden change in demeanor, and happened to see me, too. another double take.He lowered his voice, and stopped threatening. Their behavior cause the archer, closest to me, to slowly turn his head around and see me: Again, another double take. Since he hadn't said anything, he just turned back to face Don, and lowered his bow and arrow slowly.
They let Don talk again and Don told him how difficult it had been for him to get permission to hunt anything on the farm. He was allowed to shoot the ground hogs, but not rabbits and pheasants or any other small game. He was permitted to get some friends from his BP club to hunt deer during the season, but Don was to supervise all of us. Finally, they left. But, they turned counterclockwise, so their gun muzzles did not sweep past me, and they walked off the property- past another No Trespassing/No Hunting sign on the corner post, and on out across a soybean field. I walked over to the corner post, and took a hand to the top of it, prepared to use it as a rest to shoot back at them if either of the shotgun shooters tried to fire a shot back at us. About 100 yds away, the Archer turned around and looked back. As soon as he saw where I was, he turned back, told the two shotguns, and they all quickened their pace to walk out of range. Don was not armed, and his girlfriend was not happy to see me take a revolver out of my car, and put it in my belt behind my back. She didn't like handguns, altho rifles and shotguns are okay- I guess.
After that incident, she told Don that she didn't want him going down to the farm unarmed again, and told him to get one of his handguns out of his bank lockbox, and carry it with him anytime he was going to the farm. He was a very happy man, and thanked me for changing her mind. She is a city girl, and simply never thought that she would face armed threats in the country.
When I realized that the two shotguns were drunk, I contemplated pulling my gun and disarming them, taking the guns, and their wallets, and turning them into the Sheriff's office in Urbana, with a written complaint about their behavior. But, Don was the manager of the farm, and it was his call. I simply wanted us to go home in one piece, and I was quite willing to shoot all three of them dead if I had to. Because of the two shotguns, I never gave a passing sought to shooting a wounding shot- it simply was too dangerous for me to leave either of them functioning if they held a shotgun, with me only 30 feet away. All three were right handed, and they made the tactical mistake of standing too close together. The middle loud mouth could not swing his gun over to shoot me without risking stabbing his hand on the point of the broadhead held by the Archer. The other shotgun could not swing over to aim at me without bumping into the loudmouth to his right. That was the ONLY tactical advantage I had in the situation and i made the most of it, giving them the old " Dodge Cop" look to the very best of my ability. I had tinted lenses on my glasses, but no those mirror finish glasses made famous in that commercial, and in the movie, "Cool Hand Luke."But, I gave my best impression of a "junk yard dog" staring at the three. I WAS mad that they had the nerve to come back on the property and begin threatening Don, when they knew they were wrong.
Today, we would have cell phones to get law enforcement officers coming to the scene, and so we could give a running description of the men, their guns, what they were saying etc, to the dispatcher as the incident unfolded.
If you notify the Sheriff's office in advance that you are having trouble with trespassers on the land, so they can send a deputy out to get familiar with you, and with the land, check the signs as posted to see that they meet state law requirements, you will find they they are more willing to respond to your call than if you simply wait until you are confronting these slob hunters to call them. Ask the Sheriff's deputy to meet you at the land owner's house, so he can meet her, verify himself that she has not leased hunting rights to anyone, nor given anyone but you permission to hunt. If you know the men who lied to you, give their names to the officer, so he can run criminal history checks on them before he has to confront them, too.
Some officers will simply go find the offenders, and talk to them at their homes, and warn them they will be arrested if they are found hunting on the property again. Often that will take care of the problem for both you and the land lady. She needs her neighbors, but good neighbors always ask permission before coming onto your property. These guys are not being good neighbors. :thumbsup:
