While waiting for an interview today I wondered around the Presidio in San Francisco. This picture is from underneath the 101 before it goes up the the Golden Gate Bridge. The ground was slanted and a path had formed on the side of the hill. When I looked at it closely I saw that the feet that made it were tiny. Pigeons had made it. Further on down the path I encountered a group of pigeons moving in single file down the path. We all moved by each other quietly. It reminded me of how people act when you pass by them while hiking, eyeing you carefully and then nodding in acknowledgement.
