Deer hate 'em.
The movement first caught my attention. By the time I realized that it was a buck sprinting through the second-growth hardwoods 60 yards from my stand, he was quartering away and rapidly leaving my field of view. I instinctively brought the shotgun to my shoulder, found a spot behind his near shoulder in the crosshairs and tracked the fleeing form until it hit an opening in the trees. It was a fairly good shot but nothing really special, other than the fact that the buck was my 75th deer with a slug gun. I guess that's why they call them Deerslayers.
