Bohemian Club
The Bohemian Club was formed in San Francisco in 1872, composed of newspaper writers and artists (they possibly imagined themselves as "bohemians"??). It was a San Francisco Club. Later, businessmen join club. I don't really imagine the Big Four as being original bohemian clubbers. I doubt that they were considered San Francisco Businessmen. Camping trips led to the establishment of Bohemian Grove. Non-San Fransciscans were invited to the camp as guests. Probably right – the Big Four were too busy running a railroad.
