Totally agree. I live in Portland and the attitude is much more relaxed, but I make well above the typical SV salary. I get to choose my technologies, work from home when I want, my company has no interest in anyone working more than 40 hours a week, etc. I'm sure I could make a bit more with the right job at the right company in SV, but the quality of life here is so good that I won't even consider it.
If it were 80% of the year I'd move, ha! Hell, if it were half that I'd move. I don't want it to get too dry, one of the upsides of regular rain showers is everything stays pretty clean.
