Nice ride indeed....would have been well worth it on those roads...lots of concentration needed too.
Heffay, have a look at googlemaps for this route (I used to take this over a three week period in the late 70's)..Trangie,Tottenham, Nymagee, Gilgunnia, Cobar, Wilcannia, Wanaaring, Hungerford, Barringun, Weilmoringle, Angledool, Collarenebri, Walgett, Coonamble , Gilgandra... Check out the highway between Nyngan and Bourke (128 miles of gun barrel highway)...some nice roads in this lot - a lot of them all rock and dirt
