So I did some exploring today, and found pretty much the most cliche horror movie/haunted house ever.
So first I went up some stairs
Then I did some hiking
Found an underground bunker
Then this guest house type thing
Then this..
Didn't go in or very close because of all the no trespassing signs, wasn't in the mood to walk out to a police car waiting for me. But now that I know it's fairly well hidden from the street, I might try to get in next time.
