What does not see shadow or sees his shadow?

a groundhog, of course~ Punxutawney Phil. All it means is this: if the little rodent casts a shadow, there will be six weeks left of winter. If he doesn't cast a shadow, winter will end sooner. This year, on Feb. 2, today, which is Groundhog Day, he did NOT see his shadow, so it'll be an early Spring.
