I once had a tiny owl land on a branch beside my tree stand, not two feet away. It sat there for a couple of minutes then silently swooped down and grabbed a mouse. Another time, while in a ground blind, I watched a weasel run along a rail fence maybe 15 feet from me, stop, jump off and grab a mouse. Later the same day, a buck went on his hind legs and rubbed his antlers in branches maybe 10 feet away. I shot him 10 minutes later. Unknown to me, a rub had been established beside my ground blind within the previous 24 hours.
It's amazing what you see when you sit quietly and concealed in the woods....
