That is Chris Horner leading Lance Armstrong. I had a bit of trouble catching some of the action with the goons running along with the riders (half my shots have fat guys blocking them --and I was standing in the road). Anyway, we parked way down in the valley and rode 10 miles with 2000 vert to the summit of Mill Creek Pass -- I was dying with the D700, grip and 24-70 f2.8 plus water, snacks and jackets (2) in my pack.
