Sunlit steel in Chicago

So, if it weren't for Flickr, I would never have noticed or photographed this sunlit pattern. I would have regarded the underside of this bridge as a grubby, clanking urban monstrosity, to be ignored in favor of any greenery I could find anywhere in the city. Looking at it now, I see it's quite beautiful in its own way, removed though it is from my usual haunts of mountains, woods, and streams. My Flickr experience has caused me to stretch a bit and find beauty in patterns of light and structure that I would have ignored heretofore. (This is the Columbus Street bridge over the Chicago River.)
