Remember TEOTWAWKI?
That could be what you are facing.
To understand the possible consequence of an EMP attack in very realistic terms do yourself a favor and read this:
One Second After by William R. Forstchen
We have been “preppers” ever since “Y2K”. Made very
elaborate preparations, even down to getting a new
woodstove. Have used it in winter ever since. Know how to
prepare the stuff we store, too. - Our water well is fixed
for manual use, too. I learned to eat dried beans growing
up; for just about every meal except school lunches with
those giant REALLY homemade rolls. FANG has a wood splitter,
easy compared to manual splitting. Takes gasoline; we did
store some gasoline in a tank back in Y2K. Our woodstove
uses small amount of wood. At first, FANG would ramp it up
until the whole house was hot as a firecracker. I finally
got him to tone it down; so a couple of sticks of wood
burn real slow and last all day. - I’m 70, so grew up with
rustic accommodations. . outdoor toilet, Sears & Roebuck
catalog for toilet paper. - We’re still somewhat spoiled.
