San Diego is an ideal winter destination as it's often sunny and warmer than Northern California with the virtues of being cheap to get to from the Bay Area and having plenty to do. Of course, rain is always possible and the week I was down in San Diego, there was quite a bit of rain. Fortunately, I still got some sunny days to explore. Having been to San Diego previously, I did find one unfortunate new development. The zoo is no longer a good place to take photographs since many of the enclosures now have plexiglass in front the them. I did much better at the Wild Animal Park which has open air enclosures with moats to get the animals and humans apart.
