Yes they can do this, but I have never been checked like that before. The place I hunt (public land), they atleast have the decency to wait at the spot you parked til you come out. My friend I hunt with was checked during turkey season and asked theguy how long he was waiting for him to return and the guy told him quite a while. I have had this happen to me many of times during waterfowl hunting, where they would check you in the middle of the hunt, but never while deer hunting. I know they are prolly just doing their job, but that is pretty ignorant to ruin someones hunt like that.
