Thanks for the animated afternoon, Turner Broadcasting! Seems the citywide bomb scare up here in Boston today was triggered by an outdoor publicity campaign for an Adult Swim cartoon show. Turner placed weird magnetic lights in strategic locations, like local bridges, and those devices were mistaken for bombs. People in my office didn’t seem overly concerned. They followed the developments on cable and wondered if the subways (closed briefly owing to the hoo-ha) would re-open in time for the evening commute. Only two things really unnerve Bostonians these days. One is that faceless Charlie dude on the rapid-transit tickets and the prospect of sharing his fate: trapped forever underground on the train (15 minutes in the Green Line tunnel feels like forever, trust me.) The other is the hapless Boston Celtics.
