Fuse chaotically fun Pride festivities with the knowledge of NightLife and you know this event is going to be a hoot. There will be a fabulous drag performance and “tranimal” costume costume, an informative discussion on “Seven Billion Sexual Orientation” and “Stargayzing” in the planetarium. Plus, hear tales of sex-changing fish and other fascinating animals from an aquarium biologist, and enjoy activities and information from organizations like Hard French SF, Rainbow World Fund, Gay & Lesbian Sierrans, and AIDS Memorial Grove. Entertainment in the east pavilion by San Francisco icon Juanita More and the Stay Gold DJs. Additional music by Hard French DJs Carnita & Brown Amy in the coral reef.

It's $12 per person ($10 for Academy members), and you can score tickets at the door or via the interwebs at www.calacademy.org/event_tickets/
