Some sections of trail are paved with big, rough flagstones. These sections are tough to negotiate at speed because, like everything else, the stones are coated with a dusting of fine well, dust, which is slicker than deer guts on a doorknob. And did I mention that they're rough? They make the cobbles of the Paris-Roubaix look like child's play. Notice the safety barriers that keep you from plunging down the cliff into the wadi. I'm not sure whether smacking into those stones would be better than falling, to tell you the truth.
