In 2012 I was 61 and was just barely able to get the buck up in my vehicle after dragging it 50 yards.
So I figured I could hunt like that until age 70.
But in 2013 I was 62 I hunted with another old guy. I shot a buck and we could back right up to him. We lifted it in the vehicle together.
I think I could hunt like that until I am 80.
I would just have to find some younger guys to hunt with.
