Did about 2/3 of the BMC course starting at the TH rather than the church parking lot then running out to the turn off to the winery before turning back. It was cold enough that my iPhone stopped taking pics but the few I have more or less tell the story: cold, beautiful, solitary.
Fast but enjoyable course - very scenic.
Super snowy, cold, and fun! We started at the main trail head rather than the freeway exit and missed heading all the way down the Tradition Lake TH but other than that it was the same course.
