I was not a beleiver until our main IT guy got an emergency diesel rigged to his house and got an emergency food supply.
My company spent over 12 million on upgrades to insure that it didn't happen. The Operations Dept was ready to shut down the reactors at a moments notice. Most of the maintenance dept was on staff just in case.
I got some extra food, I was pretty well off in every thing else.
That was about it.
