We went to Chicago several years ago. We stayed in a hotel on the 15th floor. I was in awe of Michigan Avenue and the constant flow of traffic. Especially interesting were the pedestrians, coming and going, constantly. We stayed in Chicago three days. After observing this activity for two days, I couldn't stand it. I had to paint this scene. I awoke on the third day and proceeded to paint. I sat in my room for 15 hours and painted this scene.
