Anyone taking a tour of the famous Mark Twain Cave on Highway 79, just south of Hannibal, has heard the story of Dr. Joseph Nash McDowell and his young daughter. Many of the tour guides and visitors have actually seen the spirit of Dr. McDowell's daughter.
A new fall festival will make its debut in Hannibal on October 12. The Harvest Hootenanny will take place at Mark Twain Cave, and feature a variety of activities. This event is taking place as a fundraiser for next year's New London Park Days.
