This LA to Z post is devoted to the darker, more nefarious, side of LA's past. This excursion led me on a hike to the so-called Murphy Ranch, located in Rustic Canyon in the Pacific Palisades. Nestled amongst the hills is a hidden estate where Nazis sympathizers waited out for Hitler to come invade The United States. Here you'll enter into a bizarre world of derelict buildings and eerie staircases.
(Thanks, Matthew!)
