More than simply the northern half of the state of California, Northern California is the idea of the part of California characterized by clean air, open spaces, and people who aren't vapid and hollow. I like to think that Berkeley and Davis are good examples of Northern California. Under this definition, some portions of the Bay Area are really not part of Northern California, they are really more like Southern California, even if they are in the northern part of the state. And who knows, maybe this place exists only in my head.

Some people want change Northern California from an idea into a thing.
