South Park follows the exploits of four boys, Stan Marsh, Kyle Broflovski, Eric Cartman and Kenny McCormick, except in season 6 when Kenny was temporarily written off the show and replaced with Butters then Tweek. The boys live in the fictional small town of South Park, located within the real life South Park basin in the Rocky Mountains of central Colorado. The town is also home to an assortment of frequent characters such as students, families, elementary school staff, and other various residents, who tend to regard South Park as a bland and quiet place to live. Prominent settings on the show include the local elementary school, bus stop, various neighborhoods and the surrounding snowy landscape, actual Colorado landmarks, and the shops and businesses along the town's main street, all of which are based on the appearance of similar locations in the town of Fairplay, Colorado.
