For those of you old enough (50+) you might remember the cold war days and the practice air raid drills. If attacked, the deal was to seek out a fallout shelter and have enough supplies for 2 weeks.
The room designated as the fallout shelter in this basement was 3 feet by 7 feet. Based on the supplies, I'm guessing the users of this shelter were going to drink themselves to death.
