The Legend of Groundhog Day
Shadow, Go; Cloudy, Howdy!
The groundhog is another name for a woodchuck. According to legend, the hibernating groundhog comes out of its burrow on February 2. If it sees its shadow, it gets frightened and scurries back into its burrow. This means six more weeks of winter. If it's cloudy and the groundhog does not see its shadow, it does not get frightened, and stays outside. This means a mild spring. February is also a breeding time for the groundhogs, so that may have something to do with why they surface from their burrow.
