What the heck is sailing under the Bay Bridge right now? Sorry for the quality, it’s VERY zoomed-in.
Answer — thank you @HelenAlipaz!: It’s the Lady Washington tall ship, which is being docked at Pier 40 (at Townsend) TODAY from 4-5p for tours: http://sf.funcheap.com/pirates-caribbean-ship-tours-period-costumes-stories-pier-40/
Seriously, what a bummer! Only 4-5p on a weekday? They couldn’t move it an hour or two later so people could come by after work?
