Check out the Groundhog Day celebration featured in the classic 1993 film of the same name starring Bill Murray. Attendees gather to see area groundhog Woodstock Willie leave his tree trunk home and predict if winter will stay or go. Should he see his shadow, winter will last for six more weeks, and if not, spring will arrive early. Or at least that's what the legend says.
Though February 2 is the official Groundhog Day Prognostication, Woodstock is holding a whole week's-worth of events leading up to Mardi Gras. Check the website for further details.
