It is scary stuff and is just one of the reasons why I garden with heirloom seeds, dehydrate and can things I can get my hands on from my garden or from sales.I do have some concept of what it would be like,My biggest concern would be my insulin.I have about a year unhand but after that is where the problem comes in....
What do you think about turning a canner into a faraday cage? Maybe line one with cardboard? My garden now days is small so there isn’t much excess to can so the canners are collecting dust.
