(in progess...)
Massachusetts isn't really the sort of place you expect to have strong tornadoes, but around 7pm on Memorial Day of 1995 an F3-F4 tornado tore through Great Barrington, MA, flattening the Fairgrounds, killing 3 people, and injuring 27.
This is interesting to me because I grew up nearby, and my mom worked in Great Barrington. I spent the next few years of my life freaking out whenever I thought I saw a hook echo on the local radar. Why is this interesting in general?
This tornado spurned research into the relationship between tornadogenesis and local topography, which seems to indicate that conditions are pretty good for tornadoes in a local "Hot Spot" extending from the mid-Hudson valley to Berkshire County, Massachusetts and Litchfield County, Connecticut.

Damage pictures:
The most eerie damage was in another part of the graveyard--may of the grave stones blew over. It looked incredibly creepy when you drove past it at 6 am every morning.

It even inspired a study of torandogenesis in the NE:
