South San Diego

South San Diego is a district within the City of San Diego, and is in the larger South Bay region of southwestern San Diego County, California. South San Diego is a practical exclave of San Diego, having no land connection with the rest of the city. It is the only part of the city which borders Mexico. South San Diego includes four of the city's official community planning areas: Otay Mesa, Otay Mesa-Nestor, San Ysidro, and the Tijuana River Valley.

History
Before the arrival of the Spanish explorers, area of South San Diego was inhabited by the Kumeyaay people. The Kumeyaay, also later known as the Diegueño, traveled the region. This is evidenced by the shallow depressions in boulders that were used for grinding acorn into meal, that are found throughout the area.

John J. Montgomery achieved the first controlled flight with a heavier-than-air flying machine in the United States when he successfully flew three glider aircraft designed in the period 1883-1886 from Otay Mesa. A monument to his historic flights is known as Silver Wing Park, located on Coronado Avenue, just east of Beyer Boulevard. The Interstate 5 freeway in this region was later named the John J. Montgomery Freeway in his honor.

In 1957, the area comprising South San Diego was annexed by the City of San Diego, from unincorporated San Diego County.

On July 18, 1984, in an event known as the San Ysidro McDonald's massacre, James Oliver Huberty, a 41-year-old former welder from Canton, Ohio, committed a mass-murder of 21 people inside a McDonald's restaurant in San Ysidro. The McDonald's site was razed in 1985. The site is now home to a Southwestern College satellite campus.
