In my state if the land is not posted then it is open to hunting, so I feel that all my hunting is on publec land. I have ran into all kinds of folks while hunting including antis who have keyed my truck came through the woods singing Komby-ya and what not. the only thing I can tell you about folks like this is they wear down after a while of them hunting like this and never seeing game they will either learn to do it right or quit. As was stated earlier you should speak to them in a non judgemental way and see if maby they can use some guideance we need all the support we can get and teachint them how to be succesful will only add strength to out numbers. On the other had if they are idots good luck but they won't stick with it. I have shot a lot of deer when people like this have told me there arn't any deer around.
