The guy who came to be known as "Tractor Man" is expected in court on Wednesday. After several postponements, the U-S Attorney's Office says a pre-sentencing hearing is on for Dwight Watson. The North Carolina tobacco farmer drove his tractor into a pond on the National Mall last March 17th. He held police at bay for some 47 hours, claiming to have explosives. None was ever found, but Watson single-handedly created a traffic nightmare through four consecutive rush hours. Watson was convicted in September of making a false threat to detonate explosives and destruction of federal property. At the time, the judge indicated he might sentence Watson during Wednesday's hearing. He could get up to 20 years behind bars.
