Last year I believe the deal was that if you boot packed for two days you got one free day of quided skiing. It is not easy work in deep snow at over 12,000 ft. elevation. Since they have greatly expanded the number of unguided days next year they may change the deal to give packers unguided days instead, but that is just a guess. They just announced that if you have a season pass at DMR- Purgatory you get 2 free days of unguided at Silverton Mt. next year.
