Max,
Montana’s Big Sky area may very well have the snow you are looking for in the middle-to-end of November. However, each year fluctuates depending on the weather. Generally, most of the ski areas open up around the Thanksgiving holiday. Also most ski areas with access roads are in alpine locations that are forested. The Big Sky area is abundant with fir trees and has many winding roads which have been used for commercials. Other locations that might work include Cooke City, Bridger Bowl, Whitefish, and Bridger Canyon (on Hwy 86). Click the following link to view photos of these areas (http://www.reel-scout.com/mt/package_cover.aspx?id=33&key=645DEC1C). Please feel free to contact me if you have any further questions.
Thanks,
