Hannibal: living in the shadow of Twain

Last week marked the 176th birthday of the man who many feel defined American literature. Since his 1910 death, the city of Hannibal in northeastern Missouri has become a mecca for those who appreciate Mark Twain's work - one of the few places in the world that center on literary tourism. But it's still a city - and a small town in Missouri, at that. As part of Word Missouri, a series examining Missouri's literary heritage, KBIA's Davis Dunavin went to Hannibal to explore how aficionados, experts, tourists and residents live in the shadow of Twain.
