I think Venice beach would be great. Just go into the muscle beach area... wear TWO fanny packs, and mumble to yourself, I know I left that barbell around here somewhere...
When you're on the main sand, every once in a while, twitch like you've been shocked, and yell, 'I'm SURE it's not contagious! The Doctor was WRONG!" And scratch your arm while muttering about spiders under your skin.
You'll get a nice wide berth. And let us know how that goes for you.
