Having spent a few years hunting in Colorado, I have found if you have a reasonably maintained trial to hike in on, there is no distance that will get you away from the crowds. I try to focus on getting away from the trails as well as the roads. When doing that, I have found elk within a couple of miles of the pickup. As many have said already, go the places that are not as easy to get into (as in off trail) and you will have better luck. ---R
