I stumbled onto this slumbering beast parked on Valencia at the corner of Cesar Chavez. It was one of those hybrid electric models but was completely shut down and dark, and almost looked to be abandoned. I shivered as I realized that this used to be the old route of the now defunct, highly controversial Valencia 26 Muni line. Oh shit, this must be a ghost!
I examined the silent hull more closely and noticed that at the very back of the dark bus sat a motionless ghost conductor, staring into space, at which point I got the heebie-jeebies and high-tailed out of there. Maybe I would have investigated further had I not recently re-watched Event Horizon. Back in the safety of my room, a little research seems to indicate that this may just be an off-duty 12 or 27 (does anyone use those lines?), but I still consider myself lucky to have escaped alive.
