@Novels56 I was six when I saw the movie version of "My Side Of The Mountain", where a 12 year old goes off to live in the woods alone (with his dad's permission?!). It became my favorite book, I started learning about backyard foraging, and to this day I have a wilderness survival manual as bathroom reading for funsies. I'm shocked I don't know more, probably because I've always also thought air conditioning is nice, but please ase don't tempt me.
@DavidSalo @Novels56 It's a trilogy, I only found that out last year, haven't read the others yet, but it's in my Amazon list. Oh, and her books on animal behavior are good too, esp for kids.
