Signs of Spring???

I tend not to be an optimistic person, but you have to do your best when it's winter in Minnesota 6 months of the year. However, as I was getting in my car to go home from work, it hit me, we are inching slowly to spring. No longer is it dark when I go to work...the sun is starting to come up. But better than that, the sun is up until I get home at 5 p.m. Even my car in the middle of the day isn't the frigid cold that it was a month ago. The sun's rays are getting stronger. While the outside air says 7 degrees with a wind chill of 0, I'll take any signs of spring that there are for now.
