I have zero interest in partaking, but I'm actually all for it. One way or another, an animal raised for meat dies. Also, I much prefer seeing native species ranched, and if canned hunts for Americanos or city slickers with cash to burn means an angle to make native species profitable that's fantastic. People say it means less habitat- yea, but these replace cattle, a non-native, invasive species though we never see them that way. Americans won't pay to shoot cows, but elk, yes.
The ranched elk either dies to a cattlekiller, sledge hammer, or a bullet. None of us as hunters feel a bullet is unethical as a means of putting an animal down, so the issue is not the method, it's the practice. I'll smirk at high fence hunters, and salute the rancher- he found a good angle to make what should be living here pay. Hope it works out.
