Ooh, sailing down the Mississippi! That sounds awesome. I've always wanted to do a riverboat cruise, myself. That, or a raft :-) And yeah, you can't say that the people of Hannibal are shy about using Twain's name and the names from his works to attract guileless tourists . . .

I had never heard of Twain's Joan of Arc either! But I think I had heard of his take on Christian Science; wasn't he all up in Mary Baker Eddy's face?
