No, I've never been to Vallejo, perhaps one day. I've been to Orange County, San Diego area and LA. I could see myself living in Orange County and or San Diego. I love the oceans, ocean breeze, beautiful sunny weather, ocean cliffs, diversity, etc... But the cost of living is soo high.
I'll still visit and explore more of CA later on. There's still many places I've yet to see. I was in Cambria a while back, that's a beautiful city/town. Love the walk/trails along the cliffs overlooking the sea and sea lions...
I never get tired of San Diego....so many things to do and see and beautiful beaches...
