Every year both groups team up to build a grand parkour. The kids who change group have to to the parkour. Every year it gets bigger and more impressive.
To make sure everyone building it knows what needs to be done, I took the ideas and sketches and poured them into a Google Sketchup project and rendered it into building plans.
