Hell, it never left, as far as I can tell. And I have watched it chew up the natural landscape for decades. That's a byproduct of life as a long-distance fitness walker. You get to see American ugly and listen to its noise pollution (leaf blowers!) along the way. The photo with this posting is sprawl happening about two miles from m home in Williston, Vermont. The NY Times offers this reporting on the subject of sprawl.
