It’s really tough. Some sites only do medical and first-aid. Some do only wilderness survival like how to purify water, make a fire, find or build a shelter, get food, the signal for help, etc. Some are full of doomsday prepper crap, only about TEOTWAWKI and WROL situations, and don’t have any practical use for your life. You need to branch out and find several sites to get what you need to be a prepper.
There are a lot of websites out there on prepping and survival. Most of them are crap. Some of the non-crap ones just rehash stuff that the great ones actually write. I have a solution for you, it’s called PREPPER TRIBE with many down to earth casual preppers having mild to wild prepping discussions on youtube Try it PREPPER TRIBE
