I back-backed solo for two weeks west of the Grand Tetons - two months before turning 16. And 1200 miles from home. I’m not sure who was more nuts - me or my parents for letting me!
In college I was always backbacking or hunting by myself - winter too.
At 19 I spent three weeks solo in the Boundary Waters Canoe Area.
Those were the days! It was when I was with buddies when things got dangerous. “Hey, hold muh beer....”
Ahhhhhh, good times. Nobody lives forever, better enjoy it while you can. When I finally die there will be things I will wish I’d done, but I will only regret a few of the ones I did.
