Thanks to a small town in northern Illinois, Groundhog Day is bigger than one chubby rodent and its shadow dropping a dubious weather forecast. In Woodstock, the groundhog takes a backseat to the real cause for celebration: the 1993 Bill Murray movie that was filmed there. The Under Rocks team visited the famed town square with the head of the annual festival (and Groundhog Day movie extra!) Rick Bellairs.
