Matt Yglesias has a handy post, using NYT and Atlantic charts, which demonstrates that Illinois, and especially the Chicago suburbs, are on the vanguard of the housing collapse.

Journalism's greatest metier is fear, especially paranoid suburban fear, so expect more stories like the one from Wilmette, which taps into fantods which you may not know even exist.
