I've learned from HN discussions that there is a vast difference in what people think of as a "suburb".
Some will say it takes over 30 minutes by car from a suburb to the nearest store. To me that's very rural, I'd never consider that a suburb. But some do. So we get these disconnected discussion on how you can/can't do such and such thing in a suburb.
I've nearly always lived in what I consider suburbs. Places with single family homes and parks and playgrounds where I can very easily walk to just about every store or service nearby. The middle schools is an easy walk away for kids. High school is a bit farther but still an easy bike ride for high-school age kids (about 15 minutes).
