Finally an opening to plug orienteering in the geometry forum!
We use orienteering in our homeschool curriculum as an immediate, somatic experience in the sort of geometry only modeled by Logo's Turtle Geometry. What is orienteering? Finding your way to checkpoints in the woods using topographical maps design especially for that sport (with lots of special symbols and subtle topographical information), and using compass as needed. For our young kids there's work with scaling, rotation, step counting, planning, problem solving, the concept of isomorphism and mapping itself. See below for older students. Where can you find out more?

How's this: Given a rocky or thorny section of terrain that will require a convoluted traversal path, determine the fractal dimension of a typical traversal path and determine the most effective means of annotating this information onto the map for a running (and therefore oxygen-depleted) orienteer.
When you solve this, by the way, please send me the solution.
