I believe, but am not certain, that the Amish and old-order Mennonite are preppers of a sort, believing in always having a 6 month supply of food on hand.
If you ever have a chance to visit an Amish grocery store, about any conceivable fruit or vegetable can be purchased dehydrated, in bulk, also a vast array of grains, cereals, flours, etc., also in bulk.
I always have at home, and carry when traveling, a supply of shelf stable foods for “just in case”.
I also carry a bug-out bag, with a couple of days worth of food for myself (Cliff Bars) and vacuum sealed for the dog, water purification tablets, Mylar blankets, first aid supplies, etc., which could be another thread. :sleepy:
You never know what a day might bring, good to be prepared.
