When they were young, each June I used to take my Godson and his brother to downtown Chicago for "Transportation Day." We'd ride the commuter train from the suburbs into the city. From there we would ride a bus, the "El" (elevated subway train), take a boat ride on the lake, ride in a water tax and then ride in a "real" taxi. The second and third year we even had t-shirts made that said, "2nd Annual Transportation Day." It was always a huge hit .
