Pine Ridge is an easy to moderate hike along a double track and easy bush wacking. Any passenger car should be able to navigate to the place we parked and many would likely have no trouble driving further up the 2 track if desired. We had plenty of activity on 2M and I wouldn't expect any trouble activating 2M only. The views of the Grasslands and Central Oregon Cascades are fantastic and the solitude is remarkable for the ease of access.
