A friend sent me the following message after reading my last post:
I would add one item to the main survival kit; a copy of the US Army Survival Manual. It is available for download to an iPad or Android device, as well as in hard copy (which may be more useful in an actual emergency.)
That's brilliant advice! You can, as he said, find it in several varieties, including PDF format for printing out, illustrations and all. It has easily understandable advice and directions for surviving in all sorts of situations. A very quick search of the 'net will provide many links to it, and you can download the one(s) that you think would best suit you. I'd recommend both an electronic version and a printed one (you're liable to run out of battery power sooner than you'd expect and much sooner than you'd hope).
Some of the advice is for situations more severe than any that I hope you find yourselves in, but it's always better to be more prepared rather than less. I highly recommend that you find, acquire, and read it, and the sooner the better. Then keep a copy--preferably both electronic and printed--where you can access it when you need it.
