The U. S. Postal Service has approved a zip code and mailing address for Rancho Santa Margarita, Orange County's newest community.
A ceremony was held marking the approval with horseback riders, pretending to be the Pony Express, delivering the first mail. President Reagan, Gov. George Deukmejian and U.S. Sens. Alan Cranston and Pete Wilson sent congratulatory letters, and Orange County Board of Supervisors and Planning Commission members were in attendance along with Postal Service officials and the developer's representatives.
