Fog Horns for Train Horns

One of the things that I knew I would miss about San Francisco, especially my Richmond District neighborhood, was the fog horns I could hear lowing from the Golden Gate.  It’s a narrow path with a lot of shipping traffic in notoriously poor visibility, so there’s a fairly elaborate concert that goes on whenever the weather is foggy (read: always).  It seems there’s at least one on the shore, and if there’s more than one ship passing through, you get some very beautiful low brass chords.
