Not quite "boomer" but vividly recall air alert sirens being played for evacuation exercises to seek shelters in Norway when I was a child of I guess 6 or 7 in the late 70s. "Better dead than red." That's another one I vividly remember circulating, a bit later (early 80s). The threat of nuclear war was very real. I guess we got lucky in the end.
