I moved from a Washington, D.C. suburb to CA twice. The first time I moved to San Francisco. pros: I loved the fog, cool weather, no mosquitoes, great architecture, being in a walking city, the different neighborhoods, the food cons: the insane rents, parking restrictions, and the embracing of kookiness over normality
The second time I moved to L.A. pros: temperate weather, no mosquitoes, lots of East Coast transplants, plenty of free things to do, cheaper than S.F. cons: Santa Ana winds/really hot, dry days, graffiti, traffic, phoniness, racial conflict in some areas
If you are young and open minded, you will like CA. If you want to buy a home and raise a family, choose somewhere else.
