We have some great puzzle caches in my neck of the woods, but not too many physical challenges. Meet the Tricachelon. To complete it you will bike 20K, navagate the local lake, and climb a tree high enough to feel it sway in the wind. Grab the logo and create your own race of tricacheletes where you live. I printed up a batch of the logo in reverse on iron-on paper and left them in the final for survivors to proudly wear. Now imagine the possibility of a decachelon!
