During the summer there are free Friday night dance lessons in Jack London Square. The evening of this photo, about 200 people showed up to learn The Hustle. After the lesson, however, most people jumped in to do the Electric Slide. Oaklanders are such rebels. P.S. Don't be fooled by the clothes; this was one of those rare, warm summer nights. To take a gander at more "D" photos, visit Mrs. Nesbitt's meme ABC Wednesday.
