All of my hunting partners have flaked on me, or left me high and dry when they told me they would help me pack out. I have only ever known backpack hunting but didn't know what I was getting into pulling an elk out of the mountains vs deer/antelope. I generally don't want to burden people with my problems, but after trip #1 on my first bull 4 miles deep, I was singing a different tune.
If I had seen anyone early in the pack-out process, I would have asked for help. I train for this year round and try to optimize comfort, but after X miles, the pain is part of it and it's all mental. On the way in for my last part of camp, I saw a guy that was discouraged and hadn't punched his tag yet. Gave him all the information I could to help him, because I was in his mind state just 24 hours prior.
The only reason I didn't ask that guy for help was because that last trip in was like a light at the end of the tunnel. Hardest thing I've ever done, absolutely brutal 3 trips in, 2 of the trips were double loads out. I had been up and down the mountain 2 other times the same week before the 48+ hour sequence I punched it.
Swore I'd never do it again solo; after 3 days, that's all I've ever craved to do again, and again, and again. If I ever saw a solo backpack hunter as desperate as I felt, I would help them in a heart beat for a couple beers as long as the views up and down the mountain were epic. It's a masochistic sense of fun, and a great achievement to do it yourself though. Nobody can ever take that away from you.
