n.— «Two weeks ago I listened while Karolyn and Julia talked about the steep downhill and the series of “whoops” at the beginning of the trail. “Whoops” are like moguls in downhill skiing, they are mounds that you ride over—don’t forget you are standing up, not sitting down, absorbing the undulation with your knees.» —by Cecilie Hoffman Cecilie’s Motorcycle Journal (Mountain View, California) May 28, 2007.
