If I can just get off of this LA freeway
Without getting killed or caught
I'd be down that road in a cloud of smoke
For some land that I ain't bought bought bought
- Guy Clark (L.A. Freeway)

“In the late 1950s Carl Pfiffner spoke passionately about traversing from the Arapaho Peaks to Longs Peak along the Continental Divide. This project retains all of its original mystique and it the ultimate mountaineering adventure in the Front Range. The adventure can be extended by going from Berthoud Pass to Milner Pass. There are many variations to this complicated project and any attempt requires your creativity.” - Gerry Roach, “Colorado’s Indian Peaks Wilderness Area, Classic Hikes & Climbs” (1989)
