Chicago has a great public transit system known as the CTA and my wife and I used it almost every day during our visit. While riding the Blue Line train on our way to Millennium Park down town, I sketched this guy with his blond mass of hair hanging down over his face and reading the sci-fi book Dune. I used ink, colored pencils, and my watercolor kit with a waterbrush to add color as we zipped along. The interior bus drawing (22 Clark) was added another day while visiting Andersonville, a neighborhood of Chicago.
