"During these war years of World War II, many items were rationed including tires, gas, meat, sugar, butter, shoes and nylon hose. Other items were just plain not available. Unavailable items included pepper and pineapple (because they came for the Pacific where the war was raging) and chewing gum (because it was all being shipped to the military)."
Rationing and unavailability are two great reasons to create a food storage. Whatever circumstance we find ourselves in, storing food helps us to, "prepare every needful thing."
