California has some parts that are city and some parts that are country. When people think of California they think of Hollywood and Los Angeles, but there are areas that are just country as well. There is a large Asian community in California (either the highest or second highest Cambodian population in the states). Depending on where you travel in California you can meet a variety of people.
Living cost is pretty high, but the jobs pay a little more so it could even out. The weather in the mid to Northern area of California is very nice.
