James' recounting of the event included the image of "Fat Man's Misery" which is the rock crevice I mentioned. It's narrow and the point of entry is steep. Once you get screwed into the passage, one has to crouch low while staying contorted sideways to get under the boulder that is wedged in the gap. All part of a day of fun when you're running the course.
Thanks James. Master competitors everywhere appreciate your effort.
