For those of us not in touch with the art of square dancing, the idea seems a little, well, square, but you know you secretly think it would be really fun. Let this friendly event be your introduction. The weekend of dancing is returning from a two-year hiatus, with Los Angeles playing host for the first time. There will be two public dances, open to all for just $10. All ages are welcome, but if you get a little shy there's a bar for the 21+ crowd to help you out. If you want the complete crash course, register for the whole weekend package; it includes a square dance glossary class, a dancing orientation, "calling" 101 and even a fiddling workshop.
