1. Tribes start with holey barrel, on platform next to mat.
2. Tribes run through roped paths, up stairs, over wall to the water tower.
3. Pull tribe-colored bag to release water, filling leaky bucket, then racing back to start point, trying to keep as much water inside as possible.
4. Tribes dump their water into another barrel placed on a cantilever/SeesawBucket.
5. Repeat 2 through 4 until enough water has filled the SeeSaw Bucket (which may ALSO have holes) to cause it to lower, which causes the opposite end of the seesaw to rise, which pulls a latch, releasing the bag above the flag, which falls and pulls the flag up.
Bags at flag/signal end are most noticable in this cap, dangling down from the center of each of the flag spots. (Note also their shadows)
