Moving to south Florida 2 weeks before hurricane Andrew hit then living for a couple weeks afterward with no electricity, food, water (coffee!
) didn't teach me anything.
I had to go through it all a few more times over the years before I got the message and spent a few hundred bucks on emergency food and a way to cook when the lights go out.
I bought some of this stuff
https://www.wisefoodstorage.com/ but got it through Amazon, date-coded it and forgot about it in the closet. Never even tried it so I can't vouch for the taste etc.
Supposed to be good for 25 years and so far have never needed it but having something in the case of a major catastrophe just seems prudent,
it seems I finally learned the lesson that you can't count on government to take care of you, you need to be able to take care of yourself.
