I've never understood the whole Groundhog Day furor. If he sees his shadow, then there'll be 6 more weeks of winter. If he doesn't see his shadow, spring will come early.
I live in an area where winter starts in October and if you're lucky is over by mid to late April. Regardless of whether or not the groundhog sees his shadow, there will be at least 6 more weeks of winter. I don't think I can ever remember winter being done and over with in February. It's sure be nice though.
