I sure do. I was actually in Bethesda Naval Hospital, Bethesda, Maryland getting ready to give birth to my daughter when he was assassinated. Later that evening they brought JFK's body to the hospital, and after the Kennedy family arrived, taking over the whole top floor, the hospital was placed on lock down.
Later that evening I went into labor, but since the hospital was still on lock down my doctor, who was not on duty at that time, was not allowed to be with me. No one could enter or leave while JFK or the family was still there. Definitely a night I will never forget.
What a story! I wonder if anyone has ever done a book collecting such memories. Thanks for sharing.
