““In fact, my itinerary, as I have hinted before, was influenced not so much by Tschiffely's journey--I hadn't even read his book--as by Snow's. Snow's original plan was not to stop after completing South America but to continue either straight up to Alaska or northeastward to Washington, D.C. My insane plan was to do both, thereby "completing" the Americas and by virtue of the extra distance gained by the detour to the east coast, recording the longest unbroken walk of all time.””
