Sounds Like another case of GREEDY HUNTERS. If he does not want anybody hunting in his stand then it should be remove. It
is PUBLIC land for anybody to use any inch of that land. If you dont want people hunting were you are going to hunt then join a hunting club or lease some land.Besides that the main goal for public land is to share. There is not one thing on the planet unethical about. I let poeple hunt my stands every year hoping they have the privilage to harvest a deer.
