GAP

If I'm out of ideas for a post the easiest thing to do is to go to the graffiti-permitted section of the Mississippi floodwall south of the Arch.  There is a time of year, known as Paint Louis, when the whole thing is redone. However, people repaint parts of it here and there as they please so there is constant change. This gap in the wall gives access to an industrial area that serves the river barges. That gray horizontal streak in the lower center is one of them. The tall smokestacks are on a factory across the Mississippi in Illinois, more than a mile away.
