Every year on Feb. 2, people anxiously await the appearance of a medium-sized furry mammal who they believe can predict if winter weather will rage on or if spring will arrive sooner than later. Although it’s a rather strange means of prognostication, millions of people celebrate Groundhog Day, a tradition that is older than many people may know.The first official Groundhog Day took place on Feb. 2, 1887 at Gobbler’s Knob in Punxsutawney, Penn. In the ensuing 130 years, individuals have gathered in Pennsylvania and other areas around the United States to find out if the groundhog will see his shadow.
