One of the things you learned at Sylvan Acres after a few weeks was that there were trap doors in the ceiling of the lodge. Why they were there was a mystery to the uninitiated, because there was a large door going from the staff room above the covered area into the lodge attic, and it was much more convenient for putting things in storage. Come to think of it, there was precious little ever stored in that space, but the trap doors were a godsend.
The attic was like the crawlspace above Diggory's house in the Magician's Nephew. You could start in the staff room, push the fridge out of the way (it wasn't a big fridge), and step into the darkness. There were cross beams to stand on, and narrow boards laid across the beams for those who weren't confident about stepping from beam to beam while bent over at the waist. The story was that if you stepped between the beams by accident, you might fall through into the room below. I doubt it, since the Cooper family helped build it, and Coopers never built anything half-way. But that was the story we were told.
So, you step from beam to beam, bent over at the waist, or walk quietly on the narrow boards, trying not to make them creak under the weight of you and the bucket of water you're carrying, and soon you come to the trap door. It is in the middle of the meeting area of the lodge, before you get to the dining area, and this is where people tend to stand around if they don't know better. And if you are careful about not making any noise when you lift the trap, you can dump a bucket of water on them, get out through the staff room window, and be over the roof and into the woods on the far side of the lodge before they can figure out what happened and come after you.
The trap played a frequent role in skit nights as well, but as more and more staff got soaked, less and less of them stood around where they could be targetted, so the game got more challenging and less likely to end in success, particularly if you were after someone like Wayne, who rarely walked through the middle of the room for precisely this reason.
It was Senior Teens 1986, and the theme for the summer was tied to Expo 86 in Vancouver. Wayne had obtained large flags from a number of countries around the world, which he draped by their four corners from the ceiling of the dining hall. It was a striking display, and was very effective, but it was while he was doing the after-lunch announcements (delayed by choruses of "Why are we Waiting") that I looked at the flag above his head and thought to myself that I vaguely remembered there being a trap door right under that particular flag.
I checked it out late that night, and sure enough, there was a trap there, but you couldn't get to it from the staff room because the attic was divided into two separate rooms by a wall inside the attic above the kitchen door. In order to get up there, someone would have to climb through the ceiling and wait, and afterwards they would not have any escape. It was a suicide mission, particularly considering the target, but one well worth the cost. A perfect assignment for one of the boys in my cabin. I told them of my discovery, and was proud to see that every single one of them was ready to step up and face the wrath to come.
The next day I helped my two chosen volunteers get up through the trap during free time before lunch, passed them a large bucket, and replaced the flag over the opening. They were more than willing to miss lunch for this, and waited through the whole lunch for Wayne to start his announcements. I gave one cough to signal ready, and a second cough for go. The flag dropped behind Wayne and the water hit him as he looked up. It was a beautiful thing. The camp went wild, Wayne took note of the grinning faces looking down on him, found me in the crowd, and wordlessly communicated that vengeance would be swift. But, as I said, it was well worth it.
