I have private land to hunt in Iowa, that comes with some doe tags from the farmer. the problem is that there are others who hunt the same ground, they all call themselves trophy hunters. Every evening four or five of them, that are not hunting that day, circle the field edges of the entire farm right at or a bit after sundown. Of course, this alerts all of the deer making it impossible for those of us that are hunting to get anything. A territorial animal thing I believe, they figure if they are not going to shoot the big one, no one else can either. To get away from the harassment, I moved to public land and let the game warden handle the ethics of those that I shared the private land. A couple of them survived his scrutiny with no violations thus far, but he is working on it.
