A column supporting an old railroad trestle. It is at a curve and incline of a street and so has been painted with warning stripes. The stencils, like ink blots, are for you to interpret. The images were repeated on other surfaces around the bridge. I had some concern about whether the columns were reliable enough if a heavy locomotive rolled over my head. For local readers, this on the north (or is it west?) side of Southwest Avenue, just to the right off the westbound exit from I 44.TOMORROW: Watch the skies.
