It has nothing to do with that silly groundhog, but rather:

1. There is a light dusting of pollen on my car.
2. It is no longer pitch black out when I leave work at night.
3. The garage/rat room no longer has to be heated during the day

And most importantly,

4. The female cresteds that were paired up late in the season and stopped laying for the winter have started laying again!

I love living in the south where the spring comes early!
