Great story.I have never been that close to an owl. That is fantastic.Had two coyotes walk under me but nothing like that.One of the things I liked best about deer hunting was all the animals you got to see or sometimes just hear.A friend of mine had a doe walk up on him while he was eating a sandwich. Didn't notice her till she stepped from behind some brush about 20 yards away and just stared at him. He 'blinked' first. After about 5 minutes he dropped the sandwich and grabbed his gun off his lap, the doe was long gone by the time he got it to his shoulder.
Great story brother and from my experience with those swamp deer, their smart. Ed
