I would assume and expect that. Admittedly it has been quite a while.
Both CP and EDH were pretty nice bedroom communities but I can't even imagine how crowded they are now. Neither had the infrastructure/schools/roads to support that kind of growth. Lots of NIMBY's though. Intel is the main reason EDH has grown so fast. I'm guessing the metro area now sprawls up as far as Placerville.
Sacto, when I lived there, was at least half a day's (miserable) drive from any of Northern CA's major attractions. My middle son played hockey (at a little 1930's converted roller rink) so we spent the majority of our weekends driving to games - most being a minimum of half a day's travel (mainly to the Bay Area). Likewise, most of our air travel was either out of Oakland or SFO so many, many hours of driving. That's the main reason I love Phoenix - convenience - and so much more for kids to do (before they grew up of course). Our schools, although not reflected by the media, are far better than those terribly overcrowded classrooms in Placer County (granted, times may have changed that).
BTW, half my teen years were spent in N. CA (Marin County) so I was used to the area before moving there later on. I had half expected to see Sacto as a junior WashDC. Instead I found Jasper Junction.

I have an old high school friend who lives in Rohnert Park and drives to her Lake Tahoe cabin about once a month. She always has a tale of woe to tell every trip it seems. Too many people have definitely ruined CA (and are still working on it in AZ).
My biggest disappointment living in CP was that I couldn't listen to KYA.
