Hey Bob,
can't you guys actually hunt "no frills" for the enjoyment of the hunt, not add the inevitable technology and modernisation into a dying sport.......have I got something wrong here...if so I apologise in advance for being obnoxious.......
Last time I was outback (not that far from home either) we went walking for a few miles to shoot (cull) a few feral pigs.........great hunt, and definitely worth the effort...man, rifle, knife (oh and vegemite sandwiches - two of them)
