Where do we draw the line? That is a very good question and just why this discussion needs to happen. If we as hunters and anglers do not draw a line, it might just be drawn for us. I find the fishing thought quite interesting in that putting out a net or trap to catch fish (crabs or lobster too) is even considered fishing, and certainly the use of electronic equipment to locate is not fair chase. If the whole purpose is merely to reduce the prey to "possession" than why can't we trap deer or maybe net them from the air.
If we were still chucking spears, the invention of the atlatl would surely cause a stir among the purist. In our insatiable quest to put trophies on the wall, money in the pockets of marketing gurus and with less effort maybe, just maybe, we have lost the importance and joy of the journey. I believe that success should be in the hunt, not the kill. Hunting is not a game and there is no winning, just a journey with an ending. We take a life, or we don't. Do we have to make it easy?
