Punxsutawney phill is easily the most famous groundhog in the world. Phill lives in the small U.S. town of Punxsutawney,Pennsylvania, and is cared for by the townspeople. However, every February 2nd , Phill is placed in ground at Gobber's Knob,where he carries on a tradition that is over 100 years old. Many people believe the length of the winter can be predicted on this day, called Groundhog Day. It is said that on this day when Phill emerges from his hole, if he sees his shadow, there will be six more weeks of winter weather. If Phill does not see his shadow, spring will arrive early. Can the duration of winter really be predicted by groundhog? Probably not, but the town has a great time celebrating this tradition.
