The walks, like those in Secret Stairs, are filled with fascinating factoids about historical landmarks—the original Bat Cave from , the lake where Opie learned to fish on , or the storage barn for one of L.A.’s oldest wineries. The book also highlights the people who made the landmarks famous: the infamous water engineer William Mulholland; the convicted murderer and philanthropist Colonel Griffith J.
