Techies I know who moved up there from L.A. area, don’t make much more than they were making in L.A. Their biggest complaint is lack of good beaches in NorCal, but I have not seen any move back either, interestingly the few I know who moved down to L.A. from NorCal did not move back up, even after losing tech Job’s down here.
Bottom line I guess is if you’re a beach bum it’s probably not for you.
