Sure, you can say there are four such suburbs: Oak Park&#x2F;River Forest and Evanston&#x2F;Wilmette. To me, each suburb pair is essentially one area, but I can&#x27;t defend that argument with a straight face here. (I live in Oak Park).<p>We also have a lot of walkable, tree-lined suburbs without huge setbacks and, with the exception of blighted commercial drags like Butterfield and Roosevelt, few of the traffic setbacks and parking lot hells that this post talks about.
