Old buck

I first got pics of this deer 3 years ago and he was a mature big bodied 6 point. Every year since his antlers have gotten worse but he still has a big ole body. I seen him in person for the first time yesterday morning. His hocks are stained all the way to his hooves. Im guessing this deer is prob 8 years old considering he looked mature in the first pics I had of him 3 yrs ago. Unfortunately I can't find those pics.
