Chicago has apparently not had much of a winter, although I disagree with everyone saying that. It has snowed, and has been freezing until just the past few days. Sounds like winter to me.
Also, it doesn't really get "warm" here until the end of May, so JUST WAIT PEOPLE.
I do find it funny that these are the same folks who were predicting the worst winter in history or something and were warning everyone.
The groundhog thing is pretty silly.
