Col. Dwight Sones, left, 60th Air Mobility Wing commander, places a gentle kiss on the head of his daughter, Karina, 11, while he and his wife, Dana, read one of their family's favorite books. Karina had acute lymphocytic leukemia and was once helped by a marrow donor. Travis will host a bone marrow drive from May 14 to 18 at various locations on base. (U.S. Air Force photo/Ken Wright)
