Spanish street names in Los Angeles

A friend of mine (Tony McQuilkin) observed that if a street here had a Spanish name, there were probably no Spanish-speaking people living on it. And if a street was populated mostly by Spanish-speakers, it probably did not have a Spanish name. This is because the Spanish street names are mostly in newer areas that Anglos moved to in the 60's and later. Ironically they moved partly because so many Spanish speakers were moving into their old areas.
