Bicycles are lined up at a school in the rural highlands district of A Luoi, Vietnam. War veteran Mark Oconnor bought the bicycles for poor students in the mostly ethnic minority district so they can get to school easier. “I took too much the first time I was over here, and now I am trying to give back,” said Oconnor, 63, of Sioux Falls, S.D., who served in the war from 1970 to 1971. “It probably won’t ever be enough, but I want to do what I can.” April 21, 2014.
