The Worms are Confused (again!)

We've had an extremely unusual warm streak here in Michigan these past few days. On Tuesday it was sunny and in the 50's. The last couple days it's been rainy but still warm, very odd for early February. Mind you, this winter has been brutal up until this point, with record snow fall and many frigid days where the temperature lingers around zero. I've enjoyed the warm streak, but last night when I left school (sometime after 9:00,) I noticed a whole bunch of earthworms crawling around on the sidewalk. Apparently they are confused and think spring is here. I feel badly for them, because many will get squished by unobservant pedestrians. I spent a minute or two rescuing a few of them and transporting them back to the grassy area (weird, I know) but then I gave up because there were too many and I was getting cold. The same thing happened last year and I also reacted similarly, but that was in April rather than February...weird!
