Pretty cool. Rminds me of the time I went for a preseason scouting walk. It was windy and I was walking down a short 2 track farm lane thru the woods that went from one field to another. About 1/2 way down the road I saw a very nice blackie just waddling in my direction on my left. Head down and oblivious of my presence. He kept getting closer, and closer and then I realized the trail he was on was only about 10 feet in front of me. When he got within about 10 yds, I just spoke softly "I think you're close enough". He whipped up his head, looked at me, and I swear he turned around and took off so fast that he ran into himself. But I realized how amazing it is that an animal that big can run through the wood so quietly.
