The price of adult admission to the boyhood home of Samuel Clemens, aka Mark Twain, is $6.00. The tour is self-guided. I found the house, which has been restored to the conditions in Mark Twain's lifetime, to be quaint and well-kept. And of course, beside the house was that famous fence that Twain reportedly managed to get his friends to paint for him, free of charge.
Next door to the Twain home is the Mark Twain Museum and Gift Shop. Featured here are pictures painted by Norman Rockwell featuring some of the stories written by Twain. It was an interesting display.
