Matthew said:I think that the cave could potentially be used as a part of the storyline. It could be the part of the house where you're attempting to "escape" the house and get above ground. Put a couple hiding places, props(if any at all), and actors who are "chasing" you, trying to keep you in the house.
Not possible, as a scare actor for the event, I can tell you there are very strict policies on any type of 'chasing.'
