Its a holiday based on ancient tradition. The fact that it really isn't a "important" holiday doesn't mean it is worthless. If anyone makes money off of Groundhog Day, they are probably paying taxes. If someone is spending money on Groundhog Day, they are feeding the economy. As far as legend, I believe that winter will end eventually, spring will come, turn to summer, then to fall, and then it all starts over again. If a Groundhog says that winter ends early, maybe it will. Can anyone say for sure? Nature has its own way of signaling. Maybe she gave a special gift to Groundhogs. Maybe Phil is just better at it than others. Or, maybe his PR people are just better at their jobs. Regardless, ask the people of Punxsutawney if they believe! They will probably say they believe they have a lot of fun and make some money.
