It's good to see folks still getting out and getting it done regardless of age.
A few years ago my Dad had been fighting cancer for 5 years and it was finally winning. I got him out in the Pennsylvania woods for one last whitetail hunt and although he was in a lot of pain he made it to our stand (note: I could see the pain in my Dad's face but he never complained about it even once). A few hours later Dad was about worn out and nodding off when a deer stepped out about 200 yards away. He wasn't feeling good at all but he decided to see if he could get steady enough for an ethical shot. A minute later he was ready and said he was steady enough to shoot. At the sound of the shot the deer dropped ... shot straight through the heart.
My Dad passed away a month later ... but we both enjoyed that last hunt.
