Hugh Clark was just 18 years old when he took on a task of huge national and historical magnitude. Clark, who addressed members of the Forsyth-Cumming Optimist Club on Thursday, was one of six pallbearers who laid President John F. Kennedy to rest after his assassination on Nov. 22, 1963. Clark, a Johns Creek resident who spent most of his life as a police officer in New York, said he remembers the day Kennedy was shot and killed "like it was yesterday."
