In jovial mood and looking resplendent in his John McCrick dear stalker hat, Dad had prepared the guns for our arrival at my folks place in Hertfordshire. Having familiarised ourselves with the weapon we were shown the finer points of shotgun etiquette. "Practice firing a few from the hip in case you don’t have time to get one away from the shoulder" was his advice…. Bloody hell dad, we’re going to the Arctic, not to rob the Post Office I thought, but did as instructed, destroying an oil barrel placed strategically at the top of a pole in the field.
