I agree with the canned food. I also stock up on flats of bottled water, rotating them out monthly with new ones. You can live more than six weeks without food, but lack of good drinking water can take you down in one week. I also augment my long-term canned food storage with six cases of MREs.

You don't have to be a conspiracy theorist to be prepared for the unexpected. It is not too crazy to think that with all of the money printing going on, hyper-inflation could cause our economic system to falter in a major way resulting in shortages at stores (See Zimbabwe).
