The Rockys can be tough and steep. Especially in NW Montana and Parts of Idaho. The nastiest mountains i have hunted are right here in WNC , my home state. These NC mountains are brutal! Straight up in the worst areas with Mtn Laurel Thickets growing all over. Add all kinds of super slick leaves to cause you to slide up and down as well, it makes for some tough hunting. On top of that ,the visibility is usual terrible as well.
