Icelandic Horses for Sale near Mission Viejo, CA

About Mission Viejo, CA

Mission Viejo was purchased by John Forster, also known as "Don Juan," an Englishman by birth who became a Mexican citizen. During the Mexican–American War, Forster provided fresh horses to United States military forces which were used on the march of San Diego to invade Los Angeles. Mission Viejo was a hilly region primarily used as cattle and sheep grazing land, since it was of little use to farmers. This city was one of the last regions of Orange County to be urbanized due to its geologic complexity. In 1960, early developers dismissed most of the land in Mission Viejo as simply "undevelopable".
