Groundhog Day marks the arrival of spring and the end of winter. It's the day
where Punxsutawney Phil predicts whether spring is arriving early, dependent
upon whether he see's his shadow or not. Customers can hedge their bets and
stop by SONIC and have a Footlong Quarter Pound Hot Dog for half-price all day
