Well...during the Cuban missile crisis in the late 50s we had canned goods down in the basement in case Cuba sent missiles at the USA. Mind you we lived in Illinois so thats a helluva missle shooter thingy that can send em like 2500 miles. We had those cans in the basement for like....oh...10 years until they were ROUND and not even CAN shaped any more.
Theres always some idiot out there trying to f__k up the planet. But I live in FLorida so I got me a supply of water, canned goods, and batteries already. BRING IT ON.
