The vast California land grants of the mid-1800s have long since been divided, yet Vista remains aThe Home of the Ranchos.a Two imposing adobe ranch houses that served as the earliest centers of northern San Diego County social and business life now stand fully restored as focal points for educational and cultural events. Until 1926, Vistaas rich soil and near-perfect climate lacked one critical element: an adequate, reliable water supply. The formation of Vista Irrigation District resulted in the celebrated arrival of an ample supply of water and marked the commencement of an agricultural empire. Vista was soon the avocado capital of the world, with citrus, field, and flower crops flourishing as well. The home-building surge following World War II led to its incorporation as a city in 1963, which enhanced Vistaas ongoing reputation as a thriving, family-oriented community that excels today in commercial, recreational, and cultural endeavors.
