The history channel just did a mock scenario on this. Not too pleasant to think about,but when you do...i realized i don't have much of anything that would do me any good.

Example,Food..All that stuff in the fridge would not be any good if the power went out,so how well stocked is your pantry,and what do you have that would provide real sustenance for maybe a couple months....

Water: If the water is turned off....unless you have stockpiles of bottled or a Berkey water filter..what are you going to do.

Not that this will happen,but if it did...what do you got that is going to keep you alive?
