I've always heard the biggest jump is from 3 to 4 because at 4 their body frame is complete so all the growing goes straight to the antlers. I would say he is a 4 yr old but don't know for sure. Last year was the first picture I got of him.
Got some new pictures of him....only problem is, these aren't my pictures. Good friend of mine is getting regular pictures of him not far from me. He's hanging out around all the bean fields.
