i keep my fence locked, yesterday i just happened to be outside and a hunter was scaling my front gate....he looked bewildered when i told him i didnt want him hunting on my land i thought that the locked gate would be a clue that i didnt want drunk guys shooting guns without my direct supervision near my house.....is he allowed to just come onto private property and do what he pleases? can i put up one of those POSTED NO HUNTING TRAPPING etc signs or does that not matter either?
