Illinois State University has the Gamma Phi Circus one weekend a year. No animals, and it's completely student-run. The primary focus is on acrobatics, juggling, and other physical stunts.

Tickets are something like $15 for a 2-hour show. I don't believe any of the performers are paid and the ticket prices simply reflect what it costs them to put on the show in the absence of labor costs.

I've never been, but I know of lots of families that go every year.
