The wife is planning a ski trip to Vail in December. I'd like to get in a day or two of mountain riding. Sage Adventures has an "Advanced" tour, but the videos look like they are just meadow riding (it doesn't look like they have avy packs on). I pretty comfortable riding steeps, but am far from a technical tree rider. Does anyone have experience/knowledge of this outfit and the tour? Other suggestions? I can bring all my gear. Just need a sled and guide. Thanks.
