I spent part of the afternoon with Doug Merlino and his wife. Doug's book The Hustle: One Team and Ten Lives in Black and White just came out this week, so we talked about it. It's the story of a school basketball team in Seattle in which comfortable white students played with poor black ones; years later Doug went back to see what had happened to them all and found that the experience had played out differently for the members of each group.
Since the book only just came out I can't pretend I've read it, but it seems interesting, and Doug had interesting things to tell about it, so it may well be something you'll want to look at. Or at least visit the website and see if it interests you.
