This is a really interesting way to look at it. This weekend we were driving through the Sunset in San Francisco, and my daughter asked if it was a suburb of San Francisco. We told her technically no, because it is within the city limits. But on the other hand, most of the area was built between 1920 and 1945, which was at least 75 years after most of the downtown core (before the earthquake). So in that regard, it's definitely an early "growth-ring" of San Francisco. I like this way of thing about it. Thank you.
