While walking in Central Park with my younger son, we saw Alexander Chaplin, who starred in Spin City with Michael J. Fox. He played James Hobert, the young aide to the mayor.
I would have taken a photo, but he was with his young daughter, and I didn't want to disturb them. I think he knew that we knew who he was, and was waiting for us to say something, but the moment passed. (Alexander is on the bottom left in the baseball hat)
