Groundhog Day

I don't get groundhog day at all. The concept of it is baffling. I'm pretty sure it's based on the belief that animals are more in tune with nature, and that the groundhog is somehow especially intuitive since it actually resides beneath the earth and it therefore the chosen mascot to herald spring. This, however, is where the logic ends for me.
It is my understanding that the tradition is as follows:
The groundhog (wireton Willy or whoever) is lured from his comfortable burrow.
If the groundhog does not see his shadow and become scared, he remains above ground and it means that winter is coming to an end.
If the groundhog DOES see his shadow, it freaks him the hell out and he darts back into his home, indicating six more weeks of winter.

Here's the problem I have with this: If he sees a shadow, it's sunny which means it's warmer which is a more likely indicator of spring than a spooked groundhog.

I did not pay attention to the outcome of this festival. I've figured out that it is obsolete this year. Considering we didn't get any snow until mid January and it's only now beginning to get progressively colder, odds are we're going to have six or possibly even more weeks of winter following this day. We have global warming to thank for that. We have SUVs, meat factories, and furriers to thank for that. We have years and years of ecological neglect to thank for that.

Don't look at the groundhog; we have only ourselves to blame.
