When it hits the fan it all comes down to knowledge. That is more important and you can take more of that with you than anything you can prep for or take with you. In fact the more you know the less you have to pack. If you don't have a axe or knife you can make one if you know how. Same goes for almost every element of the survival game. With the internet all the information you could ever want and more than you could ever remember is at the push of a button. But with one EMP/solar flare/ flip of a switch that information is uncontainable. The most important part of prepping/ bug out bags is the most overlooked, a 3 ring binder you make with all kinds of information you gathered. If you don't have one, make one before the internet crashes, there is no electricity, or you are away from both! In mine I have designs for water purification systems, how to run a gas motor off of wood smoke, all kinds of antibiotics you can get with out a prescription and what they are used for. It's about 200 pages and I'm still adding to it, it's great you know what to do but does your wife know, what happens if something happens to you? It would be good for everyone else in your group to have a manual!
