For the average visitor or newcomer to San Francisco, the city's distinct neighborhoods are readily associated with the ethnic or cultural group whose imprint is most visible in the local landscape.
The rainbow flags of the Castro point to the gay (and lesbian, bisexual, and transgender) community. The Haight's tie-dye murals proclaim hippie-land. The profusion of tricolore festooned restaurants along Columbus Avenue indicate Little Italy. And the taquerias and murals throughout the Mission announce the Latino quarter. All valid conclusions to be drawn by any reasonable observer.
