The Nike Missile Site LA-88 is back in the mountains of Chatsworth, not far from Oat Mt.  It’s an impressive 450 foot gain from the parking, but it’s a pretty cool piece of Los Angeles’ Cold War history.  The site includes some great dilapidation if your like that kind of thing.  Ruins of two Buses and a car as well as a few buildings and some very sketchy entrances into dark underground places.
