I know it's impractical to build neighborhoods and homes like that in a place like the peninsula, but I would be lying if I said I didn't miss it... a lot. If you can't afford to live near work out here, and if you don't rent in an actual urban center, by the time you get home in the evenings the traffic has drained you so much it's hard to be motivated to do anything besides eat & sleep, rinse * repeat.
To your point, if you transplanted some of the nicer neighborhoods in Palo Alto or Menlo Park, for example, almost anywhere else in the country, and they'd just be slightly run down, mostly mediocre neighborhoods most middle/upper class folks would pass up in favor of new construction. And those are $3-5m houses here!
<rant off. Can you tell I'm frustrated by the auction-like homebuying process and stratospheric prices?>
