I would love to learn even half of those things. No one really taught me, I remember going camping with scouts before and another guy was catching shellfish with his bare hands and I was so jealous that he could do it. But in the UK half of its illegal and the other half requires land owner permission which pretty much makes it for the rich only as they own the land. I like the outdoors, but it feels difficult to see and even harder to do so legally. Plus no one I know now has any interest in it so its always a solo activity when I do go out.

And yeah that guy catching shellfish was breaking the law by doing it, its illegal to use anything other than a fishing rod in freshwater and that requires a license and land owner permission too.
