Getting cold fast

I told everyone after the hot snap we had back in July that there'd be frost in mid-September. Most people laughed at me. Well, it's now only 63-64 degrees out, and we are going to have the next few days be below 60 for a low... Sounds like global warning to me! That frost sure seems more likely tonight thatn it did 3 weeks ago... Oh well, we'll see who's right in the end...
