El Rio is a small unincorporated community in Ventura County, California, United States, on the northeast side of the 101 Freeway and Oxnard, and south of the Santa Clara River.
 The town was founded in 1875 and named New Jerusalem, California by the owner of general store who became the first postmaster in 1882.
 In 1885, a school and Santa Clara Catholic Church were built.
 Located near where the coastal railroad line crosses the Santa Clara River, the town's name was changed to El Rio around 1900.
 The former wagon river crossing route became the Ventura Freeway which separates the community from the commercial developments that grew up on the southwest side of the freeway.
 That portion of the historic community and sections closer to the river have been annexed to the city of Oxnard.
 Vineyard Avenue (State Route 232) is the central business district for the largely residential community.
 The population was 7,198 at the 2010 census, up from 6,193 at the time the 2000 census was enumerated.
 For statistical purposes, the United States Census Bureau has defined a portion of the unincorporated area as El Rio census-designated place (CDP) which does not precisely correspond to the historical community that is much larger with significant portions having been annexed to the city of Oxnard.
Sixes, home to approximately 14,540, is an unincorporated community in western Cherokee County, Georgia, United States, located about three miles west of Holly Springs and near the eastern shore of current-day Lake Allatoona.
 The community is located in the Georgia Gold Belt, which runs southwest to northeast along the southern edge of the Blue Ridge mountains.

 In addition, the community is home to the Sixes Mill, which was originally built around 1820 by early gold prospectors and later rebuilt "circa" 1880.
 The mill has been well preserved and is still located off Sixes Road.
 There are two theories on how Sixes derived its name.
 The first theory attributes the name to Fort Hinar Sixes, a Cherokee Indian removal fort that was located in the area along the Trail of Tears.
 The second holds that the name is derived from an old Cherokee village that was located near the Etowah River named "Sutali" — the Cherokee word for the number six.
 Sixes also lent its name to Fort Sixes, an 1830s US Army fort that served as a removal collection point for Cherokee prior to the Trail of Tears.
 Sutallee, a community that sits on the opposite side of the Etowah River (now Lake Allatoona) in western Cherokee County, also derives its name from this Native American village.
 Today, Sixes is a growing suburban community with many large, upscale residential neighborhoods, including BridgeMill.
 The area is served by two elementary schools (Sixes & Liberty); one middle school (Freedom); and two high schools (Woodstock & Cherokee).
