Isn’t MIT by Kendall Sq? Plenty of muzzies there.
MIT’s eastern end reaches to Kendall Square, but Inman square is a couple of miles away. Since the Cambridge/Boston area is well-served by mass transit, I don’t know where Muzzies cluster, although clearly they live throughout the area.
But, for events like this, density might not be a good predictor of local occurrence.
I also read that the fire started at a construction site. That doesn’t tell us much, but is where they will start their investigation to distinguish accident from arson (if you can believe what you are told afterward).
