NorCal (not the Bay Area) is much cheaper than SoCal. But it just depends on what you are looking for. In my particular area we have an active community, there is always stuff going on. And it does help that we have a CSU here. We also have a lot of great outdoor recreation. There is a lake nearby for summer and we are close enough to the mountains that snowboarding is a day trips we are also like 3 hours from everything. Oregon, Tahoe, Reno, SF... can be there in 3 hours. So going somewhere for the day isn't a big issue.
So it depends on what you are looking for beyond COL.
Is this Sacramento?
H and I want to move to the west coast, but I can't figure out a place where we won't be poor. I think we'd love northern CA if we could afford it. We do want to live in a city so that eliminates a lot of the more affordable options.
No, farther north. Sac is great, but Roseville is where I frequent for shopping. The Roseville/Rocklin area is really nice, but more expensive than where I live. Its about an hour south of me. But a fast hour, its mostly freeway.
