This small suburban town in the greater Philadelphia area is quite dull. It contains no post office and one grade school. The occupaints share a zip code with either Narberth or Wynwood. There is no shopping in Penn Valley, aside from a strip mall on Montgomery Avenue (although this is arguably in Narberth.) The big houses are usually old and made of stone, although a few new ones have been built in the past 10 years, and on large lawns, so one does not usually befriend the neighbors. The people who live here are either retired or 30 somethings with young children. Many celebrities or sports players choose to live here for the privacy. For example, Allen Iverson built a house on a private drive here.
