Legend has it that Jon aka "the ripper" has ridden more miles above 18k than any other(as seen here celebrating the summit of the Eiger a couple months ago).  However, it's his sick, notorious ascents/decents of such henious singletrack off the summits of the Trango Towers, The Grand Teton's north face, and locally, the Diamond on Longs Peak that have set him apart from the average rider.
