Interesting. Several years ago I saw a buck on my farm that looked an awful lot like this one. He actually walked right underneath me and I was watching him for probably 20 minutes, almost the whole time through my binos. So I had a really good look at him.
I attributed it just to old age, but who knows for sure. I didn't attempt a shot at him because his rack was not that big, but I later wished I would have taken him because he would most likely be the oldest deer I shot by probably 2-4 years.
