Hi all, I am heading off on a trip to the North Flinders Ranges via Burra SA, I know of two places I can find Opal in SA, that being Andamooka and Coober Pedy. Are there any other area's worth having a fossick at, I have 4X4 so can do a bit of off road driving. Also does anyone know whether the road from the Woomera to Andamooka is sealed.
