I was born in 1952 and, although I don't remember public service announcements about the atom bomb like the ones M.T. Silvia includes in her feature-length documentary Atomic Mom, I do remember "bomb drills" when I was in elementary school. At least we didn't just crawl under our desks like some PSAs recommended; we went down to the sub-basement and hunkered down in the dark. I don't remember being scared, but then I don't think I had a very good idea of what the hell we were doing.
I'm not sure anyone did.
