Social dancing is where you find it. In our persona as Wilddancers we have danced in large public squares and parks in China (as the only Caucasians present–and with the background of a bunch of dance lessons–we naturally drew a crowd, all of whom wanted to dance with each of us). And this outdoor dancing happens in the U.S. as well … especially in places like San Francisco where the weather is usually good. (A little chilly sometimes, but when you’re doing the fast-tempo version of swing called Lindy Hop you get warmed up pretty fast.) Not only is it free, but from a small group with a boombox nearly 20 years ago it has expanded to a group as large as 200 on some Sundays, complete with instructors. This all takes place Sundays from 11am to 2pm on the sidewalk behind the de Young museum in Golden Gate Park.
