I have lived in the following places:
In California: Los Angeles, Santa Barbara, San Francisco, Berkeley, Davis (near Sacramento), an Oakland suburb
New York City (Greenwich Village)
Bethlehem, PA
Portland, OR (currently)
London, UK (the old Borough of Clerkenwell)
Siena, Italy
Santander, Spain
Nice, France
I would not hesitate to tell you my favorite was London and my next favorite was NYC. Besides New York City, I'm not crazy about the east coast, really. I like California more than the PNW. Also, the job market in Portland is remarkably bad. Texas has a strong economy, at the moment. I like the bay area slightly more than southern California. I actually really like San Diego, but I've never lived there. And I think Oakland, CA is very underrated - a really great place to live in/around. However, Sacramento is near skiing and all that, but a fraction of the cost of living in the bay area. But I'm not crazy about Sacramento. Santa Barbara is great if you don't mind a slow place, but I like more excitement than that sleepy, beautiful town can offer. If you're a hippy, I recommend Santa Cruz - I have family there, and I enjoy it immensely.
