Well Illimois Bowhuntin here in New York the hunter does not have the right to cross the boundary to retrieve a deer he shot on his own land. In fact when you get your license the pamphlet they give you with it every year specifically tells you that a hunting license gives you "no special access to private land". It is unquestionably illegal here to enter private property without the permission of the landowner and that fact that you shot a deer and it ran onto that private property doesn't change anything. In fact here it doesn't even matter if the land is posted or not, you still have no right to be on it. Actually, I agree. If I shoot a deer on land I have permission to hunt and it goes on to land I don't I believe the ethical thing for me to do is to ask permission of the land owner to retrieve it. If he won't let me then I agree he is an ******* and he is ethically wrong to let the meat go to waste but it was his decision not mine. As the old saying goes, 2 wrongs don't make a right so if I go on his land anyway, I'm ethically wrong as well for knowingly trespassing and breaking the law. Here in NY if I'm caught doing this, the deer will be taken away from me and I could loose my hunting license.
BTW, I think laws here regarding this matter are good ones!
