OK. You've passed the San Francisco magazine story detailing the ways in which Piedmont is the region's best town for kids to all your friends and relatives. (To fully endorse the fair housing law, I always toss in the line, ''and we think it's great for everyone else too.'') Did you also see Forbes cite Piedmont as one of seven top ''urban enclaves''? Check it here. We're up there with Beverly Hills, Chestnut Hill, Beacon Hill, West University Park, Lincoln Park, and Park Slope. I'm getting the drift here: parks, hills, and universities. Yep, we fit that bill!
