On the subject of Mildura. I have to say that the highway signs are large and green and point North. Turning West into the wilderness is not something most people would do. Apparently there's a more dangerous problem down on the coast where buses and trucks are directed onto a dirt road off the Great Ocean Road. Don't know the details.
I remember when we were heading for Gila in New Mexico and a nice lady in Lordsburg told us to ignore the sign to Silver City and go up the mountain instead. It was getting dark and we didn't like the look of the narrow dirt road that wasn't on our map. We went the long way. Later our friend told us that the lady was an agent for the evil Force living in the Lordsburg Triangle. Whew! Lucky for us that night.
