Dave, per usual, is being very self-deprecating and unnecessarily so, IMO. He wasn't a moron on the trail and I take responsibility for his 'Nest hit as I was his spotter at the time. The IFS made it really difficult to make one turn and a tire slipped off the top of a dirty rock just as he was clearing it. The weight of the 'Nest was his biggest disadvantage and aided the slip off the rock. This is what that rock did to the next guy. 
That said, the Rubicon can kick your ass.
