Everyone has a Sport Utility Vehicle, a cellular phone, and 2.7 kids.
People even know the very few panhandlers by name.
I live in a less nice neighborhood. I feel comfortable in neither place. Though my work neighborhood, in the Sunset District, is nice and clean and somewhat interesting, you can't walk 50 feet without tripping over a stroller. Make that a double stroller, one of those expensive ones designed to look like a race car - people in that area have way too much money to spend. My living neighborhood, while much more vibrant and interesting, is just too gang-y.
