In 1992 I lived on the South Shore of Lake Michigan. I'd been out looking for that perfect seagull shot and hadn't found it. I was walking back with one shot left on the roll, and there it was, I didn't even have time to focus.
Cool thing about that photo is the duplicity of the transit system street car with the Greyhound Bus logo showing the dog running in the same direction. Then, there is a vehicle on the street with a vehicle on the sign behind it, both running in the same direction.
