Anyone heading north from Port a gutter, opps ment Port Augusta  at Pimba just outside of Woomera is a rest stop at Spuds road house, its a donation box in Spuds roadhouse. Also great coin in the slot showers $1 x 2 coins in the box at least 8 to 10 mins of a hot shower, also got to try Spuds hamburgers there a meal on there own and last time i was there was app $8;50. App 6 kms south od pimba you can call Spuds on ch 16 uhf radio and put your order in, so if your in a hurry it be ready when you arrive at Spuds. Just a warning about Spuds, there fuel is app 14 cents a litre dearer then Port Augusta so maybe fill up jerry cans to get towards  coober pedy as fuel a bit cheaper there, but my advise is ask other nomads on fuel stops are they give you the best info on prices. Hope this is a help to anyone heading towards the Alice or beyond.
