One of the first aspects that I thought of when looking at long rolling terrain, is it's lack of severity. Which to me, translates to eminently walkable. However, it would appear that the massive scale would only work for Mackenzie's 10,000 plus yard nightmares. Bringing new meaning to the term blindness, indeed. I will say that Sand Hills is as close to the scale I think we are talking about, as any course I have ever seen.
