Ian, yep!...first Bentley's plain camp. Rob Simons and a few others went exploring up there in Nov and were impressed with the riding potential of the area. Leigh Bradstreet, Bob and I all drove up one night to set up for the Christmas Camp and got to Moscow Villa at about 1:00am. I organised another Christmas camp at Bentley's 2 years later.
Your right, some of those tracks were great riding...Nunniong Trail as I think it was then known is now a big dirt road. Stopped in at Nunniong Plain 2 years ago near New Year for a look...like a bloody caravan park...people driving all around the plain, 4WDs, vans, horse floats...not as I remembered it....buggered in comparison to 40+ years ago when possibly the only visitors were likely to be Jim Commins and his sons visiting their cattle lease...and AMTRA! Forlorn Hope Track (now long gone to bikes) was a great run. You may remember Cup w/end '76 (?) when you, George Cook, Alan Jefferies David Baxter, Peter Hartman and Bruce Harvey-Fuller and I stayed at Bentley's , riding Forlorn Hope (have a few pics of drowned bikes in the Buchan), a rolling race down into Suggan Buggan and then the run back down Wombargo Track, having to carry the bikes across the rather deep Buchan River at dusk and riding back up Reedy Ck Track and back in the dark, cold and wet with pissy headlights(...on Ossa and Bulty anyway!) (we were up to our Buchan ears in the Buchan River!)
