"Ethics" are in the eye of the beholder. I make shots out as far as I know I can hit them (Caribou for me) However, this is only after a good looking over and selecting exactly what I want or let pass. Hunting in the Wiide Open' rather than trees or closed up brush demands this. I was once listening to an old man from Wisconsen , who happened into our camp with a couple Kayakers, and tell us how he was hunting with his brothers for Snow geese as a young man, when he stopped to our nets and we were cooking some Geese, after a few days of fish.Mmmmm. He said he was in a blind with his brothers, maybe in the 30's or so, and his first couple shots connected. Then he went on that he felt so sad when he examined the two of them , that when the next gaggle was comming in, he layed his shotgun down and told his brothers, "They are just too beautiful to shoot..." and he would never hunt again...... I'm sure he was very proud of himself the way he went about saying it and smiling afterwards My son, steaming chunk of greasy Goose on his fork, then asked him firmly, "What did you eat that night?" LOL!!
