Necessary reading
This is 39 pages long, but rather than saying what a little value of a book it is, let's concentrate on the message in these pages.

Yes, I'm still on the fence, but after reading this, the whole prep notion sounds a little less crazy. A week or two without power, and people will insist on you sharing what you have. A month, and they will just take it, if they last that long without water. Preparing to survive without modern crutches...money, internet, transportation...makes sense.
