Canonical date and time: The last Saturday of every odd-numbered month (January, March etc.) from 2:00 pm until the meet breaks up.
Canonical location: The Pembury Tavern
Boston roguelike meet
This happened twice before in imitation of the London meet, and it was fun, so we're doing it again. User Raxvulpine doesn't plan to host another until November, but others are welcome to if they want to.
