Sheep guts, mate I'm a clean skin, but then I dont get close enough to the yards coz I reckon I could get earmarked and branded if I did.........Ooooooo, the thought of those castrating knives scares the hell out of me. Besides I have done my apprenticeship, so I dont go near the yards to prove a point.
some times you just have to love doing airwork in the bush.......noone cares what I'm up to.
