I’m not quite ready to invest in an NBC-protected bunker, but I’ve long held the notion that a little preparation can pay huge dividends when something goes wrong.
I keep a stock of “extra” canned/packaged foods set aside in the pantry case I get snowed in or the like. If I don’t have cause to use it in an emergency, I’ll use it up and replace it with fresh stock when I get with six months or so of the expiration date.
I also keep several large sealed jugs of drinking water around. I like the 2-3 gallon plastic jugs I can get at superstores like Wally World, etc. They’re inexpensive and compact, so I can keep a week’s worth of emergency water on hand (figuring a gallon a day for me and the cat) in the back of a closet without problem.
If you have canned chicken, Veg-all, cream of chicken soup and Bisquick you can whip up a decent chicken pot pie.
