That cold in January 1976 was real! It was near 0 in Somerville in a Saturday evening with a line into the street for Steve’s Ice Cream. About a day or 2 later we had a big snow dump...probably near or a bit over a foot. I was still south of 30 and managed to stay up all night. I lived in Cambridge and walked into Harvard Square at the height of the storm-probably around 4AM. Fortunately the health center I was working at then closed and I could sleep after the snow stopped.
