Nov. 8–10 Colorado Ski and Snowboard Expo 
Colorado’s massive ski, snowboard, boot, helmet, outwear, and accessories sale returns for its 22nd year with discounts up to 75 percent off.

iCopper? A New App for Skiers and Snowboarders
Copper Mountain’s new “Sherpa” app gives skiers and snowboarders inside information about the trails they are on, hands-free. Visitors simply plug in their head phones, and the new app uses the phone’s GPS to provide guests with directions and tips about runs they’re on—and where trails have fresh powder or where they have been freshly groomed. Sherpa becomes available (for free) November 1 through iTunes.
Get Cultured for Cheap
The $52.80 Mile High Culture Pass  saves you $25 on three exhibitions and shows at places like the Denver Center for the Performing Arts, The Museum of Nature and Science (Mythbusters, anyone), History Colorado, and the Denver Botanic Gardens, to name just a few.
No snow? No problem.
Antlers at Vail is offering a zero cancellation fee on bookings now through December 13, so if conditions don’t meet your definition of good snow, you can nix your stay without a penalty.
