Hi Dennis, I was there a week and a half ago in a Subaru Forrester (Kalpower to Chillagoe). The turnoff at "Fairview" is not marked too well and the road out from Laura is rough for about 5km - the spoon drain isn't too bad. The road from "Fairview" has some sharp dips. Between fairlight and Palmerston stations the road is slow - twisty 2 tracks and tall grass but otherwise Ok. After Palmerston the road improves. The only water crossings are at the Palmer and Mitchell Rivers and will not be any problem 1/2 wheel depth at the most
