One of the most odd things about nighttime in the Bay Area is how bright it is outside. And it's not starlight. With the marine layer of clouds overhead, there's an eerie glow in the sky from reflected street lamps, traffic lights, and goodness knows what. And it's not dim, either -- it's like being out about 30 minutes after dusk. For the whole night long. It does make cycling home in the wee hours of the morning seem not so late, I suppose.
