Always important to know where the next absolutely unmistakable road is and direction it takes (N-S , E-W).It makes you wonder if William had a radio at least the abc article showed he was only around 16 to 20km of the main drag in favourable weather
Only reason I am not still lost since 1989 is that I knew the tarmac ran approx N-S and was about 7km W and just walked into the sun and then the sky glow until I hit it. Had to decide to go N or S but I got it right and its a damn sight easier walking down rhe tarmac at night than stumbling around the bush.
I had also regained composure knowing that worst comes to worst I would only have to walk back the other way from my MARKED point that I hit the tarmac.
Still took me 5 hrs to get back to car from when i realised I was bushed.
