There is The Annenberg Estate or Sunnylands, owned by philanthropists Walter and Leonore Annenberg, had long been popular with the wealthy and powerful, including Frank Sinatra, Bob Hope, Fred Astaire, Ginger Rogers, Patrick Macnee and Mary Martin. Several United States Presidents have vacationed at the Annenberg estate, including Richard Nixon, Ronald Reagan, and Gerald Ford. President Ford later bought a house in Rancho Mirage and was living there at the time of his death in 2006.
I know at one time the Annenbergs owned the TV Guide magazine.
