I always hacked out a parking spot in the privet that seems to grow on field edges. I would put my ATV in it and it seemed to work pretty well. When I was too lazy to park it in that spot I noticed deer did not react to an ATV that they could see. This year I began using a Polaris Ranger. Deer do not like it one bit. I've had several see it when walking towards the edge of the field, make a U-turn and leave. Opening day of firearms season I parked it on a bulldozer road that is a ledge. One small buck who was walking on the Road stopped, stared and went out of his way to avoid it. My old ATV was camo and the new ranger is gray and black. Maybe thats it!
