I've been thinking lately that there is no way I can be sane in a bug-out or bug-in situation without a few books. My problem is keeping them waterproof in my BOB. I certainly don't trust Ziplocks for this, and even with the rest of my gear (clothes, etc.), they're double-bagged in Ziplocks that I still don't trust. What kind of bags can I use for waterproofing my gear in my BOB that are a bit more resilient than Ziplocks but won't burn my wallet? In addition, is anyone else packing reading material in their gear? So far, I've got "The SAS Survival Handbook" and a few philosophical readings to keep me sane.
