I will be 71 this spring, I burned out myself from hunting as hard as I did while I was young. Sun up to sun down stands, tracking rub lines, scouting all year, traveling to different places and different states, I used to post about all that on here and other hunting forums. All that work paid off with my 8 mounts but it just burned me out to the point I kind of quit even talking about deer hunting. But at the same time, I decided not to quit and not hunt as hard, it got to the point where I would rather spend the majority of my time in camp with friends. That hit me around when I turned 60, about the very same time David Jolly posted that he was the same way, that's why I remember it because I was already going through that stage. Nowadays sometimes I'm fine with just hunting in the morning 2-5 days a season. Gave up bow hunting 15 years ago.
In the last 10 years, I've been hunting out of box stands or ground blinds. I gave up the climbing and lock on stands about the time I was 53 and ladder stands 7 years later. How much longer? Who knows, I have all the farmland I will ever need, and unless a record travels through I doubt I'll ever see another one again. That is the reason I shot that tall 6 a few years ago, it was something different on my wall.
One day we all will HAVE to give up. Some of us long before our bodies can't take it anymore. Failing eyesight, our hands start to shake too much, etc, etc. but it's coming. I might have 3-5 more years left in me.
