A quiet San Francisco last evening

Last night I went out with one of my buddies to shoot the Golden Gate Bridge at night. Unfortunately, the city of San Francisco is deciding to not light up the bridge at night (energy conservation, I think).
We ended up driving around in his convertible (in February!) as it was quite pleasant out and noticeably quiet. As we drove through the marina, Ghiradelli Square, Fisherman's Wharf, and The Embarcadero, all we saw were empty taxi's and empty public transit. Stores and restaurants looked abandoned at 8:30pm. And we only saw a handful of people walking along the waterfront. It was sort of eerie. Did we miss something last night? Was there a new episode of LOST on tv that everyone was at home watching?
Not to be discouraged by the Golden Gate Bridge mishap, we ventured out to treasure island and snapped some shots. It was quiet there too.. no wind.. just silence. A small crowd gathered the longer we were there.
