Rich-Many years ago when Pick and Joe Hobson owned the Bonanza they had 50 Frank Polk carved Mills machines on the floor.
They were billed as the "Fifty Generous Gentlemen of the West". I remember playing them and they were anything but generous.
I think Life Magazine did an article on the place. Later they removed the heads and had them sitting around a ledge in the casino.
I was in VC in October and the place was out of business. Too bad!
