I guess if the hunter owns or has permission to hunt the property, they can put a stand on that property anywhere they please. That works both ways of course, but if someone is already hunting a area, I see no use in setting up 50-100 yards from them. I like to have aleast a little personal-safety space between me and other hunters. I actually own land past my fence line, so if I put a stand in a tree on the fence line ther isn't much another hunter can do about me hunting "my own" fence line. Getting along with other land-owners is a good deal, but sometimes it doesn't happen. However, I would think if someone wounded a deer, then it ran through your property, they better have atleast respected you on a personal level. Otherwise, (atleast in my state) you might get to legaly tag thier deer! I agree with Mrs. Badger's good advice, a simple phone call is all it takes to be respectful when tracking wounded deer onto anothers land.
