7 1/2 years old is ancient. I have shot a few old bucks but nothing that had palmation in the rack. That is so unusual. What a trophy.
Checking out the QDMA website there was an article about old deer, their racks, and other facts. There were also a bunch of other interesting articles on other topics.
