I do agree that hunting on public land you do have to roll with the punches; however, if you know someone is scouting an area to hunt I believe you should give them the same courtesy and respect you would hope they would provide you. Personally, I would make contact with the individual who put up the stand and try to make a hunting connection; for example, maybe you guys could share notes or resources. Just and idea. Personally, when I put up blinds or stands on public land I don't mind if a fellow hunter uses it, I just don't like it when they leave trash or steal.
