This answer is from a fellow Texan who was born and raised in N California - Sacramento. First of all, you can't compare the answers from SoCal to the answers from NoCal - two totally different states under the same state name. I have lots of friends in Silicon Valley area (S.Bay to San Jose); they love it but it's expensive. It's also very liberal. I grew up in Sacramento which was more moderate, not so for the Bay Area. Just something to keep in mind. People are friendly, but not Texas friendly, lol. I lived in AZ for years before landing in TX and the most welcoming people I've ever met were here. It is beautiful, but traffic is a nightmare all the time. I worked my way through college as a runner for a law firm and routinely drove all over NoCal, it was bad 20 years ago and they've only added 20 years of sprawl since then. Ah yes, sprawl. The poster who said the CA coastal cities were indistinguishable was dead on. One town to the other, don't know which one you are in except for street signs. Similar to Dallas/Ft Worth - but much much larger. Housing is still outrageously expensive. I went to public school, but all my friends who still live there send their kids to private school. You can't pick out an area with google and a map - you have to see it. You can have beautiful neighborhoods a block from the ghetto.
Anyway, I loved Sacramento and want to take my kids there for a visit, but don't have any desire to move back.
