Now that I've graduated from college, this is the kind of school I'd like to take classes from. And I would, if I lived cloer to San Francisco.
The San Francisco School of Circus Arts (SFSCA) is just that -- a school that teaches you how to perform in a circus. Broadly speaking, there seems to be two types of classes: the basic rec-type classes for the curious and the advanced classes for the serious.
I would take the rec classes, of course :)
Classes include such acts as Chinese Acrobatics, Stilt Walking, Flying Trapeeze and Contortion (although to take the Contortion class, you need to get the instructor's permission.) Juggling Night is every Sunday. There's no Lion Taming or Motorcycle Ball-of-Death class.
If you are in the San Francisco Bay Area, the address is:
San Francisco School of Cirus Arts

San Francisco, CA 94117
