I grew up in Orange County. I just moved to VA a year and a half ago. I love the beach. I lived in San Clemente and Dana Point. I really REALLY miss it right now. It's beautiful and the weather is great. BUT I wanted to move away from it for a reason. It's very expensive. The public schools are terrible and way over crowded and the people are very into themselves, spoiled and stuck up snobs. Not everyone there is, but a lot of the people are. It wasn't a place where I wanted my kids to grow up in.
Yes, it's a beautiful area and if you love the beach, then it's even better! But, for me, it ended up being more bad things there than good.
I don't know anything about Sonoma County
