*g* I was born and raised in the area - again, it's one reason I got sucked into LKH's writings in the first place. She does a very good job (at least, if you've been there/lived there) of capturing the feel of the various suburbs.

Creve Coeur - which I can never spell right - is a fairly well off suburb of the greater St. Louis area. I think Anita's even driven to/through it a few times. Very pleasant looking place, really, and it's not hellishly expensive for St. Louis. Comfortable middle-verging-on-upper-middle-class, would be how I'd classify it.
