Corner of Stanyan and Fulton in San Francisco. The purpose of these signs never became clear to me, but I didn't have very long to consider them. MUNI arrived at this stop on time today, so I had only a minute to stand and be puzzled before boarding the bus and heading back to the Mission after work.
Update: TRAUMA turns out to be a new network TV show in progress of shooting on the streets of San Francisco – maiming and death being such ever-popular subjects, especially on film.
