Kids can do anything from riding a carousel to making an art project or dancing onstage.
There's also a mechanical bull, a family circus and characters from some popular kids shows on hand to pose for pictures.
The festival ends Sunday at 6:3pm.
Proceeds go to Child Advocates, a group that helps children in foster care.
