I did look at the belly line MC and I know what you are saying but I am going to have to stick to a year and a half to two years. I have several young bucks on my property the same way that are 1 1/2 to 2 years old. I was trying to get an idea from the whole body and although the belly does show older, there are features that say younger so I tried to round it off and take the best educated guess I could to help a fellow hunter. Just like you, I was guessing the best I could from the photo. I guess we will never know without looking at the teeth. Good Luck!! -- CDH
