I let my cuz and a very few friends ride their 4 wheelers on my place during off season. I am only up there a small fraction of the year and prefer the deer to be used to some human presence. I don't believe a little riding bothers them that much.Last fall cuz sent me a phone pic of a decent 6 point he had a stare down with across the creek. He ended driving drove off with it chomping acorns as he drove off.
