Mixed emotions

So it warmed up enough today so that it was a very cold rain rather than the frozen variety of precipitation. In between classes I decided to walk around campus and see what I could see. I hoped to find something blip worthy because I will probably be stuck in the library until late tonight after my last class.

Found some runoff with an oily slick on top. Whenever I see this I have conflicting emotions. The colors and patterns are really appealing to the eye, but the environmental effects are almost always negative. So I made a photograph of it.
