Heading to Big Sky for the first time in a week. I am looking for some first hand info. How would you compare, in difficulty, Liberty Bowl off the tram to other mountains. We have been to most of the East Coast mountains ie: Stowe, Sugarbush, Stratton, Cannon ect.. and have been to Steamboat, Vail, Cooper, Breck and A-Basin. Every mountain has their own rating system and we don't want to be caught in a situation that might be over our expectations and abilities. We can handle the blacks but most double blacks are usually more difficult than we prefer. Any advice would be appreciated!
