    "This is a dog friendly neighborhood. Several neighbors have dogs that they walk which is fun to see. We don’t presently have dogs, but we always had one to two dogs with our three kids as they were growing up. Pets definitely are park of a neighborhood community. "

    "It’s close to the creek the park and roads that go up mountain roads but I don’t like hearing the traffics from Canyon. It also feels claustrophobic to me but I’m a mountain girl."
