back before they closed Cucamonga Canyon to car traffic, there was a turn out the kids called "party rocks" and it was also where people threw cars over the edge, about 200 feet straight down. they'd end up in the stream below the first falls. once i went up to the falls and there were 4-5 cars littering the area, really added texture to the graffiti.
looking at those pics, it's worse than i've seen it.
