ANOTHER Hollywood treasure which, thankfully, I believe is still standing... at least for now. I ask you, why are these places not protected as historical landmarks? Anyways, Hollywood's original bad boy, Errol Flynn built the infamous Mulholland Farm in Laurel Canyon at the height of his career. The parties were legendary. Most interestingly, apart from the "bottomless pool" (a nine foot deep swimming pool), the house had a labyrinth of secret tunnels, the walls of which were dotted with numerous peepholes into the various bedrooms. Kinky.
Here is a cool, informative clip about the place.
