KANSAS CITY (Reuters) - The cheapest room and board in Jefferson City, Missouri, over the weekend was at the county jail, and 170 people gladly checked in. Cole County charged $30 a night for anyone who volunteered to go behind bars on Friday or Saturday night so officials could give the new jail a test run before it opened for real this week. People from three states spent the night at the jail, including some lawyers and a couple celebrating their first anniversary. Jailers tried to give the citizens the full experience. They were told to give up their jewelry, cell phones, and other personal belongings. They were booked and photographed and led into the jail commons. They could keep their cell doors open, but that trapped feeling was still there because the outer room doors were locked, said Bob Watson.
