Perry Mann's Exotic/Erotic Ball turns 30 this year. If you can imagine what a stadium full of leather, PVC, vinyl, boot, feather, nothing-wearing people looks like on any less-auspicious anniversary, think about what Boschian oddities you might see on October 23 and 24, when porn stars, burlesque dancers, lifestyle fetish devotees (which might as well be the voting populace of the entire Bay Area), and every hot university student and professor make their way to this annual human livestock event.

In addition to the two-day consumer Expo during the days, Ball Night will feature "The Blue Room" which, according to Mann, boasts "mattresses as far as the eye can see."

Past years have featured entertainment by George Clinton, Snoop Dogg, and Thomas Dolby, and this year's "surprise" guests will be booked later this summer. In the meantime, event organizers are pimping (let's be frank) an excellent Hotel/Ground Transportation/Expo package that includes VIP access to the Ball with celeb meet-and-greets for $669.
