A question for you firewood afficinadoes, being a city slicker and not have a wood burning fire in the house for heating so being a little inexperienced with different spieces I bought some 20kg bags of yellow box from Bunnings to take camping. Well didn't it burn Shit, no real coals for cooking and not much heat. Is yellow box more suited for combustion type burning. What type of wood should I be looking at for an open fire.
