Western Suburbs, Chicago: Every so often, a television show will drop in a "best of" episode where they pull from selected vignettes from the past season. To wit, I offer my collection of train sketches over the past few months of 2013. There never seems to be a shortage of subjects from which to choose. You will notice that I have several different speeds at which I capture the people, depending on how long my commute is and whether or not the people have spotted me looking at them or not. Obviously the ones who are sleeping are the easiest to do. Public transportation always gives me the best range of people sketching in an urban environment.
Where have you found your best urban sketching subject matter?
