Great article. Just got back from a three week road trip through the deserts of the southwest and I must agree that the fences are endless as are the highways dividing the open range….for our convenience.

We noticed that the highway builders have provided underground passages for rainwater that comes in heavy monsoon storms and fill washes that would wipe out highways.

Why not provide suitable underground passages for wildlife as we do for water in the washes. It simply means that we could expand the size of those culverts to allow all wildlife free passage to the other side of the man made barriers.
