i know this post is old, but i just wanted to share my experiences.
i do NOT recommend this for everyone.
i didn't believe all this hype, living in san jose my entire life and never hearing about it, so i rounded up a few friends and we ventured out.
in august we first made the trip, and a bunch of teenagers were out and about near a car, but we just went back towards thanksgiving and the car is still there...
it's a very twisty road, made several of us nauseous, so if anyone is considering this trip, be warned. bring a few bags.
towards the end, you can start seeing wooden signs that say KEEP OUT nailed onto trees, as well as a road sign with BULLET HOLES IN IT!
finally you meet a fork in the road, take a right, and that will lead you to a strange little village hidden away in the mountains, featuring a large building with gigantic windows in the center and many little cabins. there is much more, but you can't legally go any further, as there is a gate with the sign PRIVATE PROPERTY, NO TRESPASSING nailed on...
two of my friends had gone previously, and claimed to hear a young girl screaming.
i don't know if that's true, but given the environment...i wouldn't doubt it.
