Back in '97, Boston got 3 feet of snow on April Fools' Day. 2 days later it was over 70 degrees.
My school actually shut down for the day... and my school NEVER shuts down. It was the first time since the Blizzard of '78 that it closed during a semester, and it only closed then because the city government ordered it to.
I was snowed in at my then-fiance's apartment... that was a fun day
