Awesome deer! Can't wait to see hard horn pics. In my opinion, he's NO older than 4. I would have initially said 3. But headgear like that, more specifically the junk, would typically indicate an older deer. Then again, I'm not used to seeing Kentucky deer. An older deer in IA would likely have more of a gut and would be more bulky in general. The smaller frame on this one is making me say he's young. Either way, whether he's 3 or 7 he's not one I would pass although you may be very happy in the next year or two if you do pass him.
