Reston, Virginia has a walkable, compact towncenter.
But when you're there, you have this nagging feeling that something's not quite right. The water fountain is not a central gathering place -- instead, a skating area across from it is. The lampposts are not really on the sides of the streets, but are in plazas next to restaurant seating areas. The coffee shop turns out to be a Panera Bread that's on the ground floor of a Hyatt.
