Yeah, sounds like you are doing pretty good so far with that. (A lot better than me, anyway!) Definitely you will need to be prepared for the simple
basics. Things like food, shelter, security. Sounds like you got the food down alright, with hunting skills. How useful hunting will be will depend
where you live, though. The best hunter in the world will starve if there's no game.
Shelter: You haven't mentioned this one, but knowing how to throw up a tent or build some kind of lean-to or other shelter will be important if you

I'll be honest, I'm a pretty lazy guy, and I don't really keep up on a lot of this stuff. Probably the thing I should be doing is reading up more
on this kind of thing, and actually practicing it once in awhile.
This is actually a really good forum, and if you snoop around it, you can get some other ideas of things you might need and haven't thought of.
