A fairly speculative piece on MSN yesterday asks the question, “Could rising gas prices kill the suburbs?” Its talk of infill and vertical cities may be the stuff of urban planners’ dreams, but how will it resonate with real people?

Someone I know read the piece and took away this message: Housing prices in the suburbs are about to drop because everyone’s going to leave! Sweet!

And if last night’s House Hunters — in which a couple with a baby upgraded from a 2,800-foot house in the ‘burbs to an even bigger one because there “wasn’t enough room” — is any indication, it’s gonna take a lot more than $3 gas to move us forward.
