Tonight on my way home from work I noticed that the roads looked a little more dark than usual. I was a little curious as to why that was. I thought maybe I had a headlamp go out on my vehicle, but checked and it wasn't that. There are no street lights on the road I drive home, so it couldn't have been that. And then it hit me, the sky was covered with clouds because it had been raining all evening! I never really realized how much natural light we actually got when there is no cloud cover.
