... Sometimes called a Wood Chuck... remember in the movie that Bill Murray is in Punxsutawney, Pennsylvania to cover the annual celebration (Februrary 2) of whether or not the Ground Hog (this one's named Punxsutawney Phil) will see his shadow, foretelling 6 more weeks of winter if he does. It was the furry, small dog sized critter the top hatted officials consulted... Scientifically, its classification is Marmota monax... more than you ever wanted to know about an overgrown mouse, I'm sure...
