Trailer parks are communities where people live in mobile homes or trailers. These homes are often more affordable than traditional houses, making them a popular choice for many families and individuals. Trailer parks can vary in size and amenities, with some offering facilities like playgrounds, swimming pools, and community centers. Residents of trailer parks typically own their mobile homes but may rent the land on which they sit. The community atmosphere can foster friendships among neighbors, and many parks have rules to maintain a safe and pleasant environment. Trailer parks are found in both urban and rural areas across the United States.
