My niece introduced me to the joys of food storage. It comes at a good time, after watching the horrors of the Japan earthquake/tsunami/nuclear disaster. We here on Vancouver Island, are within an earthquake zone, so it is a good idea to be prepared, and if there is no situation where we would need a year's supply of food ... we have our retirement groceries subsidized.
I started with 2 starter kits, large bags of rice, powdered milk, powdered potatoes, oil, oats, raisins, canned goods, dried peas, lentils, and whenever I see something on sale, I buy extra. For instance, I bought extra toothpaste when I saw it going for $1 per tube. I am far from my 1 year goal, but close to the 3 month storage limit. I still need to purchase 72hr backpacks, so that's my next goal, plus I need to buy sugar and honey.
I have created a spreadsheet to track what I buy, so that I don't get too much of one thing, and too little of another. I have set aside a room, with a freezer, and shelf to start the storage.
