I was driving through a suburban neighborhood this afternoon. I noticed that there were no sidewalks along the street, but each home had a sidewalk that led from the street to the front stoop. The street was two lane, busy and narrow. What's the point of this sidewalk? What's the point of a "front door" in a case such as this? Are we so ingrained with "traditional" homes that function becomes void? Has anyone else noticed this phenomenon? Does another thread address this?
