Bob Edwards still remembers hearing of John F. Kennedy's death. He was a high school student at St. Xavier in Louisville, and walking into American history class."Our teacher had been on Kennedy's butt all semester," he told me. "But after that day in November, we never heard another bad word about Kennedy."Edwards remembers a lot about his hometown of Louisville: walking with his mother down on Fourth Street, the bustling downtown, and a red sign that said "Welcome to Kentucky: Gateway to the South," when you crossed the bridge from Indiana.Though Edwards left Louisville more than 30y years ago, Kentuckians still heard his voice: he was the first host of NPR's Morning Edition, and held the post for nearly 25 years.I had a chance to catch up with Edwards while he was in town helping to promote a new book, "This I Believe: Kentucky."
