Thanks to Universal Hub for pointing out one of the missing Dunkin’s in our earlier map. Here is a revision. How’s this for irony – the farthest place from a Dunkin’ in Boston is a… cemetery? What was that other map we made?

A couple of caveats:
1. I’m sure we’ve missed some more Dunkin’s (certainly didn’t get all of the airport locations exactly, for example).
2. There is a small area north of the cemetery that seems to be farther from the closest Dunkin’s, but the Cemetery is the only place in the neighborhood in the GNIS.
