Hello to any would be Hannibal Visitor(s), Hannibal is a wonderful place, and all of the spots Mr. Dempsey suggested are definitely among the destinations any visitor should make. However you should know that the Mark Twain Birthplace Shrine is every bit as deserving of a visit because it is a very short drive from Hannibal & contains many very significant Mark Twain treasures, not the least of which is the house he was born in & even the bed he was born upon. The original Clemens family carriage & many pieces of their Hartford furniture is also on display there, along with other very important relics. It is also a splendid spot for a picnic. If you delve into some history you will even travel to other very important Twain related spots within a stones throw of the Birthplace Shrine. Cordially, Bob Slotta
