The usual suspects:
Bob, Pat Villani, and Mick, probably during one of those real winters of the late 1940s, when the snow could very well be over your head when you rolled out in the morning, wearing so many layers that you couldn’t afford to fall down.
As I recall, several very large people forced us to line up for this mug shot, interrupting the important work at hand: snowball velocity testing, planning sessions with the Snow Fort Commission, and lab experiments in the creation of yellow snow. By the way, Bob and I were cleared of all charges. The guy in the middle was detained for dressing funny.
