I LOVE Big Sky - the north facing stuff on the "tram side" of Lone Peak is, in my opinion, some of the best lift-served in-bounds terrain in the country. Also love the hike-to stuff in the Headwaters area of Moonlight Basin. Also LOVE Bridger Bowl. I am hopeful that my senior in high school might go to MSU next year so I can spend more time skiing those three areas. Also, have you ever skiied Discovery? Its backside is an absolute gem of Northern Rockies steep skiing.
