Went to Idaho yesterday with the KTMtalk crowd--holy hell, what a gnarly ride. They didn't know it would be so bad, since the FS was supposed to have done some trail work.
They are more hiking trails than dirt bike trails. There was not one switchback that was rideable, I don't care how good you are. I've ridden with some extremely talented--AA class riders and seen them bulldog around ones not nearly so ugly as these. The trail was not flat in most places, which shifted your weight downhill, and it was soft, so the trail would give out under you. It was mostly made out of powdery dust with rocks in it--horrible traction. In addition to the switchbacks, there were G-outs with rocks scattered through them, rock piles, stumps right in the trail (when the trail is 6-8" wide this is a problem), and every other obstacle you could think of. Even the fast guys were beat and not having any fun.
However, I did muddle through, thanks to everyone's help, so I really wasn't in too much worse condition than the rest. I won't be going back soon though.
