On the day I took this photograph, I was wandering along the Chicago River shooting various things and reached the point where the river branches north and south. As I looked back towards the city, two CTA trains rattled along on the tracks while a tour boat passed underneath. It was potentially a cool picture, however I was in an awful position. I walked to the other side of the river to get into a better position to photograph and waited.
And then waited some more.
At some points trains would pass overhead but not with any boats on the river. Other times, boats would pass without trains. I have one picture of a tiny electric boat floating along with the train overhead. (The boat is so small it looks like a spot on the lens.)
Finally, after quite a long time of waiting, a tour boat floated by on the river as a couple of CTA trains passed above it. I didn’t have a lot of patience when I started photography, but it’s moments like this where I’m glad I’ve picked some up along the way.
