Technically, then, it's not a suburb. Depending on population, it's closer to an edge city. The fact is that suburban sprawl like one of the examples specifically decried in the article (Windy Ridge is less that 45 minutes from where I live) consists of acre upon acre of packed chipboard-and-vinyl houses that aren't designed to last without extraordinary upkeep. It's predicated upon the notion of cheap, readily available energy, never-ending road construction, and a continual stream of both upwardly-mobile homebuyers looking to move up to something nicer, and first-time homebuyers looking for something cheap they can sell at a profit in a few years.
It's simply not a sustainable model. Sooner or later the market will bust, and in the interim, there's a good chances these cheap-and-cheery neighborhoods will come apart at the seams. They aren't built worth a damn, and they're miles from critical services and commerce. It's already starting to happen here. I hate to think what'll happen if gas spikes and sticks.
(In the interest of full disclosure: I skipped right over "suburban" to "exurban" living. I have over an acre on the outskirts of a small town about 25 miles from the nearest big city. So I'm happy out here, too. But gas bills are already putting a crimp in my lifestyle, so that might well change.)
