My dad and I used to go to the library. On the side of the library was a big yellow sign that said "Fallout Shelter." I asked my dad what that was, and he said it was a place to go in case there was a bomb. I remember being really worried because I knew I could fit behind that little sign, but I didn't think my dad could.
Later it morphed into the idea that there was a tunnel leading from the shelter to the street that came out right behind the sign, and the sign was about 15 feet above the ground, so when you left the shelter you would just 'fall out.'
