Let me tell you where I am coming from, literally and figuratively. I used to be a "fat" guy. I live in North Central Wisconsin at 250' elevation. My first Western hunt was antelope in my 30's. I was out of shape (holy hell a lot), but I have a good head game. I got on the scale one morning after that hunt and looked at the scale,wow. That day changed my life. I started eating clean, portion control, running and HIT. I lost a ton of weight. I had been researching my first elk hunt for two years and the time was nearing. Western Idaho, DIY, public land, 2 weeks to hunt. Other than learning how to read maps I had done EVERYTHING on my own. I used GE and had my camping spot picked out. I had a route created on my GPS. I pulled into that trailhead just before daybreak. As I shouldered my pack and gear (117#) for two weeks I was listening to elk bugle within a mile (mistake 1 ) I hike that pack for 13 hours that day through the roughest, nastiest, blowdown bull$hit I had EVER seen. I pitched my tent in the dark that night. Less than 24 hours later I was standing over my first elk, a 5 point. DIY,public land, first time ever in Idaho, first time ever in the mountains, first time ever elk hunting. I broke that bull down (deboned and hung) and started out with the first load, even after literally being 100% exhausted the day before. It was HOT and DRY that trip. Temps got into the 80's....however I knew what I had to do to keep the meat safe, and I did it. It wasn't easy, but I brought home 298# of boned out Idaho elk meat back to WI. I've done it every year since, and sometimes twice a year. Don't be to hasty to say can't or impossible people.....and apply that to everyday life also, not just elk hunting and see where it leads you.
