Going up the ski lift at Big Sky, you see one particular tree off to the right side full of Mardi Gras beads, bras and panties. It seems tactful and fun since it's only on this particular tree. Most ski lifts I've been on have something similar with usually the bras and panties.
The hotel/lodge doesn't have a business office even though they tell you they have one. It is located inside the Mountain Mall on the second floor. You can print out documents and fax them from here. A fax costs about $3. If you only print a few pages, it's free. Printing boarding passes is also free. They also let you use the internet but not sure what that costs.
Big Sky has a Town Center paper and website with information about the city, tourism, happenings around town. There can't be too much going on but if you're visiting Big Sky, you want to know what's going on. Check it out!
