Currently the town has no manufacturing industry and no industrially-zoned land. Its location on the North Shore of Massachusetts provides easy access to the Atlantic seashore with its reservations, beaches and boating. The town includes many historic houses and pastoral landscapes. It also has a rich equestrian heritage, which remains strong due to the influence of the many horse farms and of Myopia Hunt Club, which holds frequent equestrian events, including polo most Sunday afternoons.
