For one, the sunny Southern California destination tempts its citizens to bare more flesh on the average day than most other locales. The city is also all too often aligned with the latest crazes in fitness, diet and new age wellness. Hollywood often finds itself in cahoots with the latest idolized bodies, and any subsequent surgical attempts to imitate said bodies. And a little north in the San Fernando valley, you'll find one of the original hubs of the porn industry.
Yes, if there were any destination bursting forth with opportunity for a body-centric art exhibition, the city of angels would be the place.
