Hannibal: Sarah Andersen of Auburn, Maine, covers her ears as the horn blows aboard the Mark Twain Riverboat in Hannibal, Mo. Andersen, who studied American Literature, came to see the town Mark Twain grew up in. "I can visualize ol' Sammy Clemens wandering around those streets and across the hills up there on Cardiff Hill and over at Jackson Island. It's great to
see it and I'm glad I came." Mike Dean / Mike Dean/CNHI News Service
