Driving from Port Augusta and the talk turns to penguins. King, fairy, etc. and which work best in a camp fire. They all have different incendiary properties and you do need to pick carefully, depending on what you want to do with the fire. Do you need a steady even flame to cook with, or a large hot fire to talk and drink by? For a big social fire, King Penguins are best.
These are just some of the things to be dealt with on a trip across Australia by Holden. The trip is, of course, significantly different if you're in a Ford. Or a Daewoo.
