410,000 people enter Washington, DC each weekday (as of 2005), the second-largest increase of any American city. But if you walk around large parts of downtown in the middle of the day, you might not think so. So many buildings face inward, with their public spaces in central courtyards cut off from the fabric of the city, feeding their workers in indoor cafeterias, leaving the streets and public squares (such as the park around the northwest entrance to Judicary Square) remarkably desolate. Even the new condos along Massachusetts Avenue have car-oriented driveway loops but no stores or restaurants facing the sidewalks. Is this really city living?
