I once looked at a property for sale that struck me at the time as being a former cock fighting and prostitution operation. It was located back up in the mountains out in the middle of nowhere. The driveway went for a ways through the woods until it opened to a large clearing. It was covered with grass, but you could tell it used to be a parking lot because of the large, lemon-sized gravel covering it. About 100 yards away was a steel building with a ring on the ground in its center. Next to that building was a 2-story building like a motel with really small rooms (no plumbing). Something like that couldn't have existed unless the local sheriff was being paid off. This was in the same neck of the woods that a former girl friend lived. She told me how in a former time the sheriff would show up at their door to get his payoff to let them keep selling pot. I suspect the same kind of thing is going on in CA.
