Ken enthuses about our flat roofed sleeping accomodations. (NB: flat roofs make very little sense in Yellowstone, given the 150+ inches/year of snow accumulation. Our later research found out that the park employs a full-time winter employee -- ala Jack Nicholson -- to remove snow from the cabins. This past winter, this particular employee failed to detain the pine martens entering the lodge/restaurant, where they soon took up residence causing $75,000 of damage to the carpets and linens. One cabin was also crushed, but this is par for the course.)
