Norden, during Norden's visit to Walter Reed National Military Medical Center in Bethesda, Md., June 12, 2013. Norden and his brother Paul, each lost a leg and were burned and pelted with shrapnel during the second blast while shielding other spectators following the first bomb explosion during the April 15 Boston Marathon bombings. Long said he was on patrol in Afghanistan's Kandahar province last year when the vehicle he was riding in encountered a roadside bomb. With media members listening to his story, Long told Norden, and his girlfriend Kelly Castine, far left, that he's just now getting used to his recently fitted prosthetic leg.
