Well after messing around a bit and following the pylon track we ended up getting back on a sand track near Fossil Rock which resulted running into soft sand. (Above)
So tyres down to 15 psi and thought may as well do Fossil Rock, so off we headed
Off course I made the mistake of hesitating while negotiating one of the ridges and got stuck (below). Fortunately Terry helped me reverse back by pushing on the bull bars (he's a strong lad), and on the second attempt almost flew over
Great day out
