If you swing by Blue Frog Bakery today, take a gander at these Halloween-themed cupcakes.
These seem to be the very definition of "trick-or-treat." They're just one of many signs of Halloween in the neighborhood today. Also on tap: The JP 12th annual Dog Parade and Fashion Show at 1 p.m., and the trick-or-treat Halloween stroll from 3 to 6 p.m. More details on both events below. In addition, the annual Halloween bike ride starts at 6:30 p.m. at the Green Street T station.
