My biggest bust was back in February, 1969, also known as the 100 hour storm. The route 128 belt had between 25-40", with a forecast of about a foot or so and not a 4-day storm. Of course there was no effective model guidance back in those days, and satellite images were relied on much more. This picture shows that it wasn't just the Blizzard of 1978 that made a mess of route 128.
