The small rural community of Bonita is nestled in the fertile valley of the Sweetwater River. For over a century, families from nearby San Diego and Chula Vista have built secluded homes on large lots carved from the pioneer ranches that emerged in the 1870s on Rancho de la Nacion. Ulysses S. Grant Jr. and the Marstons and Allens built homes designed by architects such as Irving Gill and William S. Hebbard. They relished the rural equestrian lifestyle of their valley, and resisted the modernization that began after World War II with highways, shopping centers, and subdivisions.
