Walnut also happens to be the name of a small city in southern California. Not to be confused with Walnut Creek, a small city in northern California, Walnut is a fairly quiet bedroom community consisting of mostly middle class families. Expect to see lots of trees, freshly mowed lawns, and expensive "personalized" tract homes.
