I'm not too worried about the Tobacco Roots since I never ski there, but I am not a big fan of rotten base layers regardless. Skinning around the West Yellowstone area last Christmas was literally like being in a thunderstorm, with 40" of new snow collapsing for a half mile in every direction as I moved along. We shall see...early season snow sucks ass for those of us that will be spending the majority of our time in the backcountry.
