Conversation so far:
What are the California properties in relation to William Randolph Hearst?
Beginning in 1919, William Randolph Hearst began to build Hearst Castle, which he never completed, on a 240,000-acre ranch at San Simeon, California.

Question: Did he own other properties in California?
Self-contained rewrite: Did William Randolph Hearst own other properties in California besides Hearst Castle?
