We’ve all heard of Punxsutawney Phil, the little furry guy in Pennsylvania who comes out, sees his shadow, and declares six more weeks of winter. Then there’s Augustus T. Groundhog, better known as Grand Rapids Gus. He’s Phil’s much more interesting cousin. Unlike Phil, who it seems can only see shadows, Gus has much better eyesight and can look at a calendar on February 2 and know that spring doesn’t start for six weeks. Gus suggested that instead of lamenting over six more weeks of winter, we should EMBRACE the cold and snow and do something fun. And so, the Groundhog Day Marathon was born. Source
