On Tuesday, Aug 15, we will hold the banquet at the resort's Vista Hall from 6:00-9:00pm. This will be an exciting celebration of Montana's old west spirit, including dinner and dancing.

Options for travel from the nearest major airport (Bozeman, MT) and the resort include: airport shuttle, rental car, and through the hotel.

For individuals and small groups, the most cost effective option is likely Peak Shuttle.

For those traveling in larger groups or in coordination with other conference attendees, there are discounts available through Karst Stage (base price plus additional cost per person) and Big Sky Bound (cost is per ride, not per person) that may prove more cost effective. Additional options may be found here and here.

For those renting a car, there is free parking at the resort.
