We’re travelling through Queensland in convoy with friends. Moura is a purpose built coal mining town, neat, tidy and quite spread out. As we leave town we pass the Queensland Nitrogen Plant. Being city slickers and wondering what this large plant is and what QNP stands for, we get to chatting over the UHF radio with our friends. Suddenly a voice comes on the air and explains. “It’s Nitro.”  We’ve all drawn a blank and asked “what’s Nitro?” “Fuckin’ fertiliser mate.” Says the voice. These UHF radios are really handy.
