While I was looking for a map to see when street sweeping occurs on the far away block I parked my vehicle, I discovered what this building is. Just a substation. A pink substation.
This vault cover at 37th and Judah made me wonder.
Why would City College be linked all the way out here? Probably obvious to most, but CCSF, which I always associate with the school, really stands for City and County of San Francisco and DTIS is the Department of Technology and Information Services. Perhaps it's a link to the N Shelter which announces when the trains are allegedly coming?
