Nice buck. I don't think he's very old though. Even in the summer, the older deer in the herd are distinctly greyer in the face. I'd say he's a 3 1/2 year old, maybe 4 1/2. Not sure how quickly your deer in your area grow. Also, did you happen to get any straight on picks of him looking at the camera? If so, take a look at his nose. A lot of times, deer over 4 1/2 years of age have what they call "Roman" nose. They are narrow looking in comparison to their head.

Regardless, nice buck. Now, lets see him with your tag on him.
