I was talking to some people yesterday that mentioned that there was some people hunting a place in Iowa that they own. They noticed that there was some vehicle there from out of state hunting on their property. They went over to confront them and tell them to get off their land. The out of staters pulled their guns on them and kicked them off of their own property at gun point. You have to be very carefully when you do this...apparently even on your own land. Some people are crazy enough to pull anything to hunt even if it means doing a lot of illegal things. I would definitely contact the proper authorities before you take matters into your own hands. The land owners didn't even get the plate number on the vehicle parked on their land.
