I watched an owl attack the same duck decoy 2 times in a river.

My buddy and I watched a huge buck mule deer watch a hunter. The deer knew the hunter was there and moved around while keeping an eye on him. The hunter never knew the deer was there. Finally the hunter started walking towards the deer and the deer just went over the top of the mountain and disappeared. Later we met up with the hunter and he asked us if we saw anything and we almost died laughing!
