i have three favorite tough sections 1st is from rocktober mountain enduro..small section that is striaght up a boulder field,video doesnt give you any sense of steepness or the amount of boulders,and this is shot from the bottom..every year it gets worse to get up clean,this is from 2007! when we raced in 2009,there wasnt much dirt left to ride on,all rock to climb up on..
