Groundhog Day

Since 1887, it has become an American tradition to have our weather forecast for the coming weeks decided by the most unlikely of creatures. Every year on February 2^nd^, people gather in the small town of Punxsutawney, Pennsylvania (which is about 75 miles NE of Pittsburgh) to see whether a groundhog (named Punxsutawney Phil) will see his shadow. According to the tradition, if Phil sees his shadow (which he “sees” 90% of the time), we will have six more weeks of winter.
