In 1981 I inspected the last rations of the Cold War Nuclear bomb shelters in the Knoxville, Tennessee, area. The crackers were rotten, the water unpalatable and contaminated and the storage amenities were unusable. The inventories were kept by the Tenn Air Guard at McGee Tyson and spread in several shelters in the Knoxville area.
On youtube there is a govt film about living in a fall out shelter.

Were the items in the video similar to what you saw?
Thank you for taking the time to reply. I find this stuff fascinating.
