Well, between Fidel and the Soviets, one of my early memories is sitting at the dinner table (actually, I was probably half across it and in the way) as my dad stuck the compass point in the Mall in DC and drew concentric circles with that as the center...
Then I learned about warhead yield, blast effects, and that we'd likely have to go south by boat to Virginia from where we were if the balloon went up.
I always knew where the life jackets were after that.
Thanks, Fidel for that warm and tender memory.
Thanks, Dad, for being so patient.
