John loved his religion, his birthplace St. Louis, golf, bird feeders and had the eye of an artist. He was especially proud of his military service to his country during the Korean war. John flew forty-three missions over Korea as a flight engineer and mechanic in the Air Force and believed that every person who serves, regardless of their assignment, is a hero.
