Weird. Very weird.
Around here, all of East Cobb is just a disaster area (from an aesthetic standpoint). Not only do all the subdivisions look alike, all the HOUSES in the subdivisions look alike. When we were looking for a house, we went into one well regarded subdivision in East Cobb -- we drove down one street and I told our agent "Don't bother - let's go." All the houses were on one plan - center hall Georgian with an ell. Some had garage on left, some had garage on right, some had ell on left, ell on right. Painted different colors (mostly), but even the LAMPPOSTS in the driveways were identical. Shades of Stepford!
We wound up buying a semi-abandoned infill house in Vinings, which is an old non-uniform suburban community.
Nothing’s changed in Princeton proper, although US 1 (especially from the Plainsboro line down the the Trenton border) is now all strip malls and office parks. Lots of construction, especially since the 1980s.
