Loudoun County, VA is full of areas like this. County code mandates sidewalks in new developments, but the developers end them at the edge of their land, leaving gaps.  It&#x27;s ridiculous - it shouldn&#x27;t be that hard (or expensive, over time) to link communities in a sane manner.  Heck, Reston, VA managed to stay reasonably walkable&#x2F;cycle-able and most of it was planned in the 70s.
