That's what I have in mind as Pyrenees Ranges is really a unique place. But I think it's been graded, isn't it?
Just went on the trip there over the weekend. It seems a lot of tracks around that area were graded but a few have been left. The little climb on old bluff seemed to be untouched. Many said the left side was nearly undrivable (proved them wrong) and the Middle was still a challenge itself. Great place, can't wait to go back!
