"For many weeks, it was like a phonograph record," she says of the assassination. "Now, it is pushed back into the back of my mind, never to be forgotten. But I can bring it back up any time I want. "It'll be with me forever, but I don't have to live with it every day." Kennedy, with wife Jackie at his side, smiled and waved at the crowds from the back seat of the presidential limousine. Up front, Nellie Connally and her husband, Gov. John Connally, beamed at the Texas welcome. "No longer was my life as peaceful as it had been, and I'm careful even now. I look behind me occasionally and I watch out for my children," Connally, 84, explains. She's written about her experience in a new book, "From Love Field: Our Final Hours With President John F. Kennedy." John Connally died in 1993 and Jackie Kennedy died the next year of cancer.
