    "Atherton is a quiet town with stunning trees, beautiful homes, and a very low crime rate. The Atherton town administration is incredibly helpful. The police once returned my lost puppy. Atherton is conveniently located near major employers, Stanford University, restaurants, shopping, and between 280 and 101. "

    "It is a spacious quiet place full of friendly people. Dog owners would love to see each other walk their dogs. People also jog, go on walks, and roller blade. Dog owners are usually friendly and responsible."
