Freeze-dried food, stored water and Berkey water filtration units with spare filters.
Buying cases of canned goods and rotate as used.
I try to keep a minimum 5-year to 10-year supply of food on hand. I have relatives that do the same and they also keep sealed buckets of dried wheat, rice and corn. I have been off work for as long as two years at a time and lived off my food storage which really helped.
