so a 5 gallon bucket is just a couple of week's worth of food, at best, for one person. It takes quite a few 55 gallon drums of food to last one man for a year of heavy duty survival type of living. As in 6-7 of them. And they have to be buried, and they have to be either metal drums, or wrapped in several layers of rat wire. and the burial means that they have to be 35 gallon drums (1/3rd more of them) inside of 55 gal drums, so that they don't rust out so quickly. This also requires that both drums be inside plastic drum linerrs. The holes must be lined with several inches of gravel, so that moisture and the freeze/thaw cycle don't crack open your drums.
