I have tons of books, SHTF bags in my house, car, etc.
Best books I read were by Cody Lundin and Rawlings on the subject.
I have good gear, not cheap shit that most 72 hour kits comprise of.
The only thing I need to get is a Katadyn filter. After that, I am close to being good to go. Need a little more dryfood, but most else.
