A nice sunset the other day in Chicago

I don't know why Chicago tends to get these kind of sunsets in the winter - the ones with the long horizontal bands. Perhaps they happen everywhere, but I don't notice them quite exactly like this, except in Chicago during the fall and winter. I remember as kids, the teacher in 3rd or 4th grade, or so, had us do a watercolor of this very scene - trees with the bands of sunset behind it. I still have the picture, and have been meaning to frame it one of these days.
