I can relate the body giving in on you and have had my fair share of physical ailments lately. I was going to pass on deer hunting last year due to doctor's and wife's orders but my nephew of all people walked into the shop and said" If I have to carry you to the swamp I will". Way to guilt the old boy into hunting with a statement like that and I tend to take things like that personally.
Long story short I hunted as much as I could. Weather was 75 degrees all week and hunting sucked and deer were not moving had 2 by Saturday night which we are usually tagged out by Tues or Wed. Sunday morning comes finally a little frost in the air and I did not want to get out but sucked it up. Turns out the two old boys, myself and another fried my age with bad knees, that were not supposed to be hunting were the only ones to get up and we both shot bucks that morning. Luckily mine went down in the field and I could drive the truck to it, loading was a chore but it got done. Buddy buggered his knee worse, by being to stubborn to call for help and is just getting around the surgery now. Needless to say the youngsters took a lesson in humility and fortitude that morning.
Just when you think you are done you may have one more hunt left. Good luck and if that chair needs a push I am sure I or a few others here may be able to help. Yes we have the retired hunters come by on butchering day and they all leave with a feed of backstrap and we take pride in doing so as many were instrumental in implementing and maintaining the local muzzeloader hunt we have today.
