They may have turned around and gone back to Karijini .They may decided to park the car and walk the rest of the way .They may have taken the car to a mechanic to check it .None of the above choices .
What may they gave done after seeing the circuitry ?
From Karijini , it 's 200 kms on a dirt road , through the deserted town of Wittenoom . We had all the windows up for most of the trip not only as a precaution against asbestosis but just to keep out the clouds of red dust that we were drawing behind . At one stage we had a quick rest stop and happened to look under the van . Dragging along the ground beneath it was most of the electrical circuitry , slowly being worn away on the rocks and dirt .
