With Bert The Turtle in 1951 many of us grew up in the 'Duck and Cover' era remembering the 'Fallout Shelter' signs. The government instilled in our minds to be prepared so in the 50s and 60s it was big business building and supplying/stocking bomb shelters today however is different, the government now deems it unnecessary (evil) today the government wants us to rely on them not self-reliance.
