After reading all this I realize I am inadequately prepped. I keep an old coat and a snow shovel in my car, and during tornado season I leave the cat carrier open near the door to the shelter (if I were to get the carrier out the cat would disappear, so the carrier has to be handy).
For Y2K my preparations were a couple packs of slim jims and some hot-hands hand warmers.
I am really not prepared for the electricity to go out, whenever it is out I have no water (on a well) or heat/air-conditioning. If there was a bad storm I'd probably have to be rescued and taken to an emergency shelter.
I guess in a way I am prepped just by living in a country that has plans for emergencies (tho the early covid pandemic showed some scary gaps in the govt actually doing what their plans say).
Supposedly the US govt (or some other agency, FEMA maybe) has stockpiles of food, insulin/meds, etc. And there is the Red Cross.
Maybe unemployment insurance and food banks are the most useful preparedness for the common problems.
At work for our computer systems we do disaster recovery exercises frequently, transferring operations from facilities in one state to another.
I never hear the Preppers talk about salt, I think it is interesting that toilet paper, which is not at all a necessity, is stockpiled but they don't mention salt.
