I store it in the small 6 gallon metal trash cans available at Wal Mart.
When I buy the rice, I buy small bags (typically 1 or 5 pounds). Since I have many small bags, if one goes bad for some reason, probably bugs, the others are not as likely to be affected. I squeeze the bag to see if it holds pressure right off. When I put the bags in the can I include a chunk of dry ice to displace the air in the can before I seal it.
I also put some of my spare electronics devices in the can between the rice bags. It is a very good EMP faraday cage. Be sure to keep the device from touching the metal side of the can though.
Is there anything you freeze (to kill bugs) for a time before storing it, such as rice or flour?
I recommended a good supply of dehydrated H2O. Very simple, just add water.
In addition to food stuffs don’t forget the “barterables”. ATF = alcohol, tobacco and firearms. With UN troops occupying American cities during a famine I’m sure a pack of cigarettes and a quart of whiskey could buy you a weeks worth of food.
