Gas prices pique interest in Walk Score

Web site rates 'walkability' of homes, neighborhoods

With gas prices surging over $4 a gallon, a Web site that scores the walkability of a neighborhood is enjoying what its developers hope will be more than just 15 minutes of fame.

The Web site, Walk Score, sizes up the stores, restaurants, schools, parks and other destinations within walking distance of a given property and uses that information to calculate a walkability score between zero and 100.
