Somewhere along the way we came on a Holden with a car trailer, with another Holden on the trailer. The latter had no wheels. We stopped, as one does. He was immensely grateful. He'd used up all the wheels on the spare car as he'd blown out tyres as he drove. He'd had a parrot, but it had died in the heat. He and his dog were still alive but not very happy. We dropped them off somewhere further south. That was probably early to mid December (we were on the Eyre Peninsula at Christmas). No Aircon in our old Falcon. We opened the large front air flap and suspended ice cubes on the blast. It worked albeit sensorially interesting - drops of iced water in a furnace breeze. Those were the days :-) 1977?
