Todays photo features a "twopher" (yeah, that means two for one... or something like that). Be sure to view the subsequent photo.
This photo was taken in front of the Trolly stop at Market & Powell, San Francisco inbetween trollys coming and going (and as you can see, one is coming right behind Tina).
You strobaholics.... get on with your thing...
