Boston Marathon bombing survivor Marc Fucarile, seated, talks Saturday to his son Gavin, 6, at the finish line of the Boston Marathon.

At least 2000 people, including survivors and first-responders showed up to participate in a Sports Illustrated photo shoot to commemorate the one-year anniversary of the bombings. Fucarile, a 35-year-old roofer from Stoneham, Mass., lost his right leg above the knee in the bombings on April 15, 2013. He was the last survivor to leave the hospital.
