Professor, I am right there with you. I turn 58 next month and have learned the hard way that I need to be strategic and pace myself. Early bow season in Georgia can mean temperatures in the mid 80s, with 100% humidity, with a 1000 vertical feet of climbing and descending off trail with a weighted pack on your back. I am taking the entire first week of bow season off from work so I hope to be able to invest the time to create an opportunity. I still enjoy the struggle and the suffering.I did the same thing, and it worked, but it took a couple of years for me. In the meantime, I killed two mature mountain bucks, so there is that. It will kick your butt. For me, the worst part is getting back on some ridge and trying to get out through a couple of miles of blowdown. I have learned some of that lesson. there is so much land and I just love to explore, plus, when you bear hunt in the mountains you really have to scout and hunt at the same time. So, I tend to wander too much and it really tears me down. This year I will cut that back because the fatigue is cumulative. I about did myself in at Cohutta last year, and I did not recover till after the season.
