Watcher

Was thinking about that photo of the mossy trail through the woods, and how weird and creepy it would be if that was a part of a haunted attraction (though safer and not as lawsuit-inducing). And instead of actors in the woods interacting with patrons and trying to point-blank scare them, what if they all kept their distance. Dark figures moving slowly through the woods, keeping pace with the viewers, and allowing themselves to be seen, but just in the shadows, and in silence. In particular, ahead of each group of visitors would be a cloaked figure, about twenty or thirty yards away. Alone. And with a costume similar to a Reaper - but not as obvious. But the catch would be that the costume would be reversed, made to look like it was facing the patrons. In reality, it would be an actor slowly walking ahead of each group, walking in the same direction, with a mask/custom-made costume attached to his or her back. Always looking like a figure slowly floating ahead of them, and facing them. But always moving away from them.

In the darkness, I'd imagine that would be a really unnerving effect.
