Groundhog Days Festival kicks off its 27th annual celebration with a host of activities only days after actor Bill Murray filmed a “Groundhog Day-”related Jeep commercial on the Woodstock Square in time for the critter’s emergence this weekend. The Awakening of the Groundhog is set for 6 p.m. Thursday when Woodstock’s official Groundhog Day mascot, Woodstock Willie, will make an appearance on the Woodstock Opera House stage, according to festival organizers. The 27-year Woodstock tradition pays homage the 1993 classic film “Groundhog Day,” which featured scenes shot in 1992 in the Woodstock Square.
