Back in 2000-ish, that area used to have a scarezone there for a few years called THE SWAMP. It was great.
There is still one more deadzone though, and it's back by Bigfoot Rapids. That also used to have a scarezone back there, can't remember the name, I think it was there for only a year.
But even theeeeen, there was still deadspots.
I think if CarnEvil quadruples their clown count, the back part of the park should be more frightening. Usually I stroll there and see maybe 5 or so, maybe 1 trying to scare me.
Meanwhile, Ghost Town is a nightmarish fog filled monster haven from park entry to Calico Square.
