It took a while, but I finally had some luck
I've watched this particular buck for a few years, and based off the past several years of trail cam photos of him I assume he is 5 1/2 years old. I'm not an official measurer, but he should gross in the upper 170s pretty easily.
I also posted below some pics of the one my father in law took from the same farm from the exact same stand. After going back through old photos, I actually think his buck is 6 1/2 years old. It is hard to appreciate the mass of either buck from the photos.
It is honestly pretty bittersweet to see both of these bucks go. I run cameras year round and enjoy much more to the deer hunting than merely killing them. For me, it is a year-round affair and it is knowing bucks like this exist that motivate me to put the time and the effort in. I absolutely love the whitetailed deer, and feel extremely blessed to get to spend the time with one of God's most wonderful creatures in their natural environment.
Good luck to all of you still trying to fill a tag
