VTT with Bertrand

Bertrand is my neighbor, and an extremely skilled mountain biker.  Every time I ride with him I end up crashed out in a bush or on the ground, and today was no exception.  We rode up to MSM (~1400 vert feet of climbing), during which I was barely able to keep up with him, and then descended via trails,  The catch was that the upper half was all under a layer of snow, which led to several spectacular crashes.  I am making progress, but slowly.
