The color of the rocks up in Karratha and Dampier are so red you'd think you're on Mars.
This is “that stupid flag” that we forgot about all the time. Since this vehicle is “Mine Spec” (meaning it passes all the extra safety requirements for a mine site) it as a flag on it so that you dont get run over by those big trucks.
Funny thing about that flag was that we'd forget it was there – until, say, we pulled in the gas station. All of a sudden we hear this “wacka-wacka-wacka-wacka-wacka-wacka”. D'oh! Stupid flag was dragging on the underside of the gas station roof. Feeling stupid I got out and had a look and instantly was relieved to see the marks all the other flags had left there.
