I don't think he was talking about leaving a pile of pee under the guys stand. Really all you can do is report the 4wheeler use. And good luck getting anything done about that. As Predate said, the best method for public land is get where no one else goes, the deer will shop up their once pressured. Don't overlook small section either. One of my best public land spots is a narrow strip of woods running between a field and the road. No one goes into it because the overlook it due to it's size and being close to a road, but the deer like to hide in there because of that.
