    "We live in a rural area where our dog has a fenced yard, but can also run around the non-fenced area and it is safe. Our dog is welcome at the transfer station, city hall, along with the many parks in the area. Most people clean up after their animals, although there is always a few that don’t. "

    "We live on acreage down a private gravel drive. We love the fact that we see wildlife each day, are not annoyed by speeding cars passing our home, and love the tranquility and peacefulness of our neighborhood. We have the best of both worlds, living in a rural community, and work in the city of New Haven which is about a 30-minute drive. "
