Crazy on the CDT

From walkingcarrot.com:

“Then we met two mountain bikers pushing their bikes up the pass at the headwaters of Meadow creek just northwest of Cottonwood mountain. They started in Lima and are headed to Chief Joseph pass. While we plead guilty to the label of being crazy enough to hike the CDT, the thought of mountain biking, even part of this trail, should label someone as certifiably insane.”

Who could they possibly be referring to???
