Not illegal. Property owners have an action in trespass at their disposal, should they pursue it. It is not illegal per se to trespass. Learn your local laws before you shoot.
People hunt in and around my property, and I have no problem so long as they respect the safety zones and hunt safely. So I don't care, maybe I'm the minority here.

Not unethical. I can shoot into my neighbor's ground without a second thought, as I am a permittee. I think of myself as a pretty ethical guy.

I do work, and I do have a piece of land. I do shoot on it as I see fit. Our family has 5 really exceptional gentlemen who hunt on our land. They're relatively poor, and can't afford their own place. We give them free use of a camp, food, heat and electric. I just feel bad because I can't accommodate more guys. Where I live, more and more hunters are being displaced by greedy people like you, and it just isn't right. There are enough deer to go around, so quit crying about a guy sitting by your property line. If I could afford to buy my own gamelands for them, I would.

You greedy hunters have an inferiority complex. Are you that scared that somebody else will get one and you won't??

Yeah, and you would be going to prison for attempted homicide in any jurisdiction.

I used to take your side on this issue. After a few years of watching and listening, and one extreme case in Wisconsin, ignorant, greedy landowners need to be called out.

This deer greed has gone too far, and I just think that it wouldn't kill you all to let a guy or two wander through your ground without going postal. Obviously, the Angry Landowner's Assoc. has spoken.

Pretty entertaining thread, eh?
