ATV's have practically ruined one of my areas this season. The neighbor on the adjoining property also bowhunts his land and this area. Without question he has changed their patterns to almost no patterns at all. Its not so much when he hunts but when he decides to do a little riding. For me, ATV's are ok for early/late season scouting and dragging a deer out. Other than that they are nothing but a nuisance.
