Middle son went to high school at what most would consider elite hs (top public not private) and most all parents were "elites" (some were not) they were also very much about the green environment issues. Always loved it when picking up son from soccer practice on perfect 68/72 degree day. I'd get out of the truck go sit on the grassy hill to watch end of practice the elite parents would part their cars by the chain fence, engine on, windows rolled, AC turned on to watch thru the windshield.
