It sounds like you're lucky you didn't kill an elk across that canyon. How would you have gotten the meat out? On the question of aggression vs. caution -- it depends on whether you're just passing through, or will be hunting that same terrain, and the same elk, repeatedly. I too have doubtless been overly cautious over the years. But I generally hunt the same few square miles for a month, getting to know the individual bulls quite well. Thus, my first concern is not to spook them, and not to leave scent all over the place, and overall, not to let them know they're being hunted. If I were doing a walk-through hunt where I wouldn't be pounding the same area over and over, I'd be more aggressive. In my experience, even cow calling is starting to backfire as often as it works. My most common reaction is to be ignored. If I can't find a wallow or spring or other feature that's being visited daily, my preferred stalking strategy is simply to move in on the bugling without calling at all, maneuvering constantly to stay downwind. Ain't it great fun? dave
