Jeff McC was at Zeitgeist for the Tamale Lady's birthday when he peeped some Sutro Tower ink.  I'm pretty sure this is the most definitive proof that a person, at one time or another, lived in The City.  Yeah, I guess you could get a tattoo of the Golden Gate Bridge to prove you lived in the East Bay (??), but that's some tourist shit.  Your tattoo is only cool if people east of Antioch have to ask you what it means.

Seems like Sutro tats are not all that rare.  Elly has a pretty epic one of her back:
