Good neighborhoods are more than the house. A short drive to a free festival, a zoo day, or a movie night at a local park is part of why families love living in Orange County and Los Angeles County, and part of what to look at when you are deciding where to live. If you are thinking about a move, ask yourself which of these events are close to the neighborhoods on your list.
