A stretch of Boylston Street around the Boston Marathon finish line was blocked off Sunday morning so that the Globe could capture a photo that will mark the one-year anniversary of the April 15 marathon bombing. More than a hundred victims, doctors, nurses, runners, store owners, firefighters, police, EMTs, politicians, and Red Sox and Bruins players all gathered for the photo. Mayor Marty Walsh and former mayor Tom Menino were there with Governor Deval Patrick. Slugger David Ortiz, in a tan cowboy hat, showed up with a smile despite the team’s extra-inning loss Saturday night. Another cowboy hat was there, too, on the head of one of the heroes from the tragedy, Carlos Arredondo.
