    "Lots of dogs owners. Dogs are leashed and most owners are top tier, clean up, and treat dogs well. No dogs left outside barking. "

    "Having a Caltrain station in Belmont is very convenient. Three tech companies pick their employees up at bus stops at El Camino Real and Ralston. Wonderful neighborhood. "

    " My favorite quality of San Mateo is its location. It's at the cross section highways in the SF Peninsula and a short drive to/from anywhere. CA 101 North is a short drive to San Francisco, South to San Jose. CA 92 East heads over the San Mateo Bridge to the East Bay, Oakland and Berkley. CA 92 West takes you over the hill to Half Moon Bay and some of the best surfing in the world. CA 280 was at one time called the 'Most beautiful Highway in the World' and is still my favorite way to travel the Bay Area."
