Just wondered what people thought would be the best cereal for keeping handy in hard times?

Total cereal for it's nutrititve content, though not sure the shelf life will hold up.

Grape Nuts never seem to go stale, long as they are kept dry.

Raisin bran can get tough to chew after a couple years I noticed.

Cheerios turn into Styrofoam after a year or so, depending on the humidity level.
