I was visiting Pier 24 Photography yesterday afternoon taking in photographs from the Collection of Randi and Bob Fisher.
When I arrived at the front door of the exhibit hall, I noticed with amazement that there were old railroad tracks alongside the pier. These tracks are obviously no longer in use. If you look straight down on the tracks you can see water from the Bay underneath. I took the above picture with my phone so you can't see the blue waters of the San Francisco Bay just beyond the tracks unfortunately but I did manage to tilt the shot so you can get a glimpse of the underside of the Bay Bridge.
