Basically I would think in terms of mixed contents for five gallon buckets. I always use Food Grade buckets only combined with good Mylar bags and oxygen absorbing packs. By mixed contents I mean bags of rice (white) beans various types along with pasta products etc. this way you do not expose five gallons of rice or beans all at once. This extends the overall life of your food supplies.
You make good sense about starting with a years supply of preps. Without putting any emphasis on myself it is easy for me to forget that I was born in 1953. What we call prepping is what my grandparents called normal living. They never stored water, of course we had plenty of it back then, but food, preserved, canned, dehydrated, powdered, and in just about every other form was everywhere in their lives. And they were not big farmers, just small timers with no bills, no agenda, no nothing except the ability to have plenty in the toughest of times. Those people taught me a lot and I thank Christ for them every day. Well, that’s enough about me. Best wishes to you and keep up the good work.
After 9/11, my dad filled a duffel bag with some energy bars, a couple gallons of water, some penicillin, and a map. Amid scaremongering headlines about imminent anthrax and “dirty bomb” attacks in the city, he wanted to have some supplies on hand in case we needed to get out of Brooklyn fast. Were he to assemble such a bag today, he’d likely stumble on a number of companies promising a more wholesale brand of disaster preparedness: a box full of shelf-stable freeze-dried meals, to be revived from their dessicated state with the addition of boiled water.
