the saddest poem in San Francisco

Biking to work this morning, I passed a Muni bus going the opposite direction. The screen on the front of the bus said: "MUNI TURNS 100"* and then as I passed it, the screen changed to say, "OUT OF SERVICE."

If only it could have been like this.
*I am paraphrasing. It may have said, "100 Years of Muni," but I think you see my poem.
