My observations at HOS Williamsburg, HOS Tampa, HHH at Uni, and Haunt at KD lead me to believe that none of them have really broken the code on path scares. I am increasingly coming around to the view that the costs, terrain, and logistics make effective scares zones out in the open untenable in most locations.
I think you and I and many folks here would agree that path scares and scare zones are ineffective because they have failed to scare us, personally, but every trip to HOS and HH, I see PLENTY of people who do. Yes, many of them are teenagers, but they seem to make up a decently large percentage of HOS/HH visitors, and I'm sure as far as the parks are concerned, and the scare actors are concerned, they're doing a GREAT job of scaring people. I think they could do much better, but I'm sure they have little to no interest in stepping up their game because what they're doing now works for your average event atendee.
