Last year I had this spot that I would go to for an afternoon hunt. Going in a good percentage of the time I would spook deer. There was just no way to get in without spooking some especially when you’re walking on potato chips the whole time. Because I was in full camo I don't think they really knew what I was and they definitely did not get wind of me but they saw enough movement to take off. Well what in learned is that these particular deer and it could be and usually was 10-15 of them would come right back within a couple of hours. Going in I would see them run right up the mountain and then come back. I could not believe it but it happened several times. So you never know what they will do but I agree with GregH it depends how badly they are spooked.
