Joseph Swide has written a story for the Classical about Rainier Beach's propensity for producing professional basketball players:
Locally, [Rainier Beach is] known as the best place to get Vietnamese food. It is perhaps less well known as an astonishingly fertile cradle of basketball talent, although it's that, too. This is a place that has produced more current NBA players than just about any other place on Earth—as many as Brooklyn, Manhattan, and the Bronx combined. That's where we're going.
I had no idea. Did you? If this is news to you, you really should go read Swide's whole story.
