Yeah if you compare the two deer, he is definitely older. It's funny that when looking at deer that aren't from your area we make assumptions and at times an older deer may have similar characteristics of a younger deer. You can't single out one or two characteristic (shoulder, swayed back) and make a decision. This is one of those deer that just plain looks old to me. I would be willing to bet that he's 6+. It would definitely be a good one for the experts!
