>General survivalism thread i guessThere's a lot of woodcraft/bushcraft stuff online, the 10 C's of survival is a good starting point for an outdoors survival pack (each C is a category, not a single item). It depends what you want to do and how long you'll be out for the direction you'll go with what you pack, but you'll probably want to add some hygiene stuff and a mess kit. Then you'll want some first aid stuff, including common daily things you take for granted when home like pain pills or anti-diarrhea medication or chap-stick. If you're packing a firearm when you go outdoors, you'll want stuff to treat a gunshot wound (so a typical IFAK with a TQ, prepmedic on youtube has some good content for putting that sort of stuff together). And whatever tools and stuff you get, you'll have to be trained on it otherwise it could be entirely useless to you. And if you really want to be prepared, you should have either a sat-phone or some sort of satellite device to get cell service because shit happens even when you're fully prepared and trained. No reason not to use modern technology to survive.
There's woodcraft/bushcraft courses you can take, stop the bleed courses, and any other sort of training like that would help. Learn to hunt, fish, trap, raise animals, and grow food. Actually taking a course and doing a hands-on use of the information with an instructor will be more helpful than just watching a few YouTube videos. Or you could watch some videos and simply try doing it in your backyard, even if you keep having to go back in your house to get something you forgot, better to forget in your backyard than out in the wilderness where you're now risking hypothermia, dehydration, exhaustion, or death. /out/ would probably be a better board for asking this though.
