Now here's a great survival accessory for the Christian or non-Christian for that matter............a foldable topo-map style New Testament, waterproof and tear resistant. Why didn't someone think of that for survival manuals? Always a good idea to have reading material along for a survival situation and this seems ideal. Not affiliated with this site, and it has just been released.
