    "Not enough sidewalks and the cars are always speeding. Downtown is fairly dog friendly, yet I don’t understand why pets are not welcome at the farmer’s market; at least nobody enforces the rule."

    "Not enough access to public transportation. No busses, train stops, pick-up areas. Not enough sidewalks on busy main road areas. Including Chesterfield road, Lovers Lane, Roxbury through Corey Lane/Riverview, Upper Pattagansett through Ancient Highway, Bridebrook Rd. , Plants Dam, Dean Road area. Should all be accessible easily on foot. "

    "People here are mostly gentle and kind. My cat went missing once and the community exploded with kind words and support. Always plenty to do between Rocky Neck, the boardwalk, and all the cozy shops and parks. Beautiful scenery at all times of year. We moved here during the winter and the cute little street lights on Main street were done up like we had stepped on the set of a Hallmark movie."

    "Cute little beach area. Private beaches are not huge but do the trick. The beaches are on the river not the sound. Not all pet owners are courteous with cleaning up after their pets. Making changes such as fencing or a carport are next to impossible due to zoning regulations and neighbors making a big stink. Who wants to live with that?"

One way in and out-no crime at all-ever! Stone wall entrance that winds bordered with hiking trails and water views of Niantic Bay."
