The only time I saw President John F. Kennedy in person was on the Monday before his Friday assassination. It was in Miami Beach, and the president was being driven in a motorcade to a speaking engagement. He was in the open limousine that became his death car four days later. The motorcade was moving at high speed--around 50 mph--and so I got only a fleeting glimpse of him, smiling and waving to the crowd, as the procession whizzed past.
