We had a big blizzard in 1979 in Baltimore (and one in '78, too -- the one that's still legendary in Boston).
I had a Bronco 4x4, and I drove lots of people (doctors & whatnot) to and from work during the '79 storm. I also drove some friends home from Hopkins Med School in the thick of that storm. I have a vivid memory of the sky (really the whole world-- since conditions were near white-out) lighting up purple from lightning, followed by long, rumbling thunder. It was... kind of terrifying, actually.
Rather inexplicably, we started to sing Drop Kick Me, Jesus (Through the Goalposts of Life) when it happened.
It was the Seventies...
