This has our attention. I've downloaded the GPX files for my viewing map pleasure.
I'm also going to view this thread which should give us some good intel: Cascade Discovery Route | Adventure Rider
It was interesting to note that in the photo gallery, the person who posted these pictures (RobG) is the same RobG who was (did ish) ride the beginning of Moab 2016 last year. He left before we arrived so I never actually got to meet him. He hasn't been heard of on the forum since as best as I know.
Anyway, this CDR thing looks very interesting and we'll see if it's doable or not when I get done reviewing the Advrider thread.
Thanks for posting this.
