I've put up a new post on our special project site, with a live version of the popularity map shown below. This tabulates the suggestions we've received about small cities to visit -- weighted by numbers of votes:
More explanation at the site. Plus an only-in-America (blurry) photo of American abundance, swimming-pool-dept. UPDATE (Saturday morning, Aug 10.)
