People Watching

People-watching is one of my all-time favorite things to do. The best people-watching happens when folks are "in their own world": at airports, in dark movie theaters, on sidewalks, and in cars. This gentleman was sitting, daydreaming while waiting to travel from Austin, TX to Boston, MA. I especially loved his glasses. I wonder what he was thinking about?

Do you like observing others? Where is your favorite people-watching spot?
