Let's take this neighborhood disaster equipment a step further. Fire is one of the biggest threats in any war, grid down event or isolated area. You can not depend upon outside resources. You'll have to deal with it yourself.

Are you prepared???
Here is an excellent series by southernprepper with loads of good info on this subject.
"The time for war has not yet come, but it will come and that soon, and when it does come, my advice is to draw the sword and throw away the scabbard." Gen. T.J. Jackson, March 1861
