I'm not sure about other states, but in Missouri, you are required to have your stands out of the woods after the 1st of February(not exactly sure on the date). That keeps people from "claiming" spots. I wouldn't intentionally hunt an area that I knew was being hunted, but I also wouldn't feel bad about hunting a great area that others are hunting too. I ended up killing a buck off public ground a few years ago. I scouted the area pretty good, found my tree and came back the next day to hunt it. Got settled in early and was hunting by 3:00. Around 5:00 I heard some movement and there was a guy coming into the timber from the opposite direction of where I entered. He proceeded to climb up a tree that was about 90 yards away. We both saw each other, but stayed to hunt. He never even saw the buck I killed until he was running away. That hunter was very friendly, stuck around and helped me blood trail the buck until we found him(which wasn't very long). I'm sure it could have worked out differently, but the honest truth is that I had no idea he had a stand in there.
