I don't know that I would hunt in a high wind, as it might result in a wounded animal. However, as far as practicing or shooting in tournaments in a high wind, I think a person could be his own worst enemy. True, you're not going to shoot as well, but neither is anyone else. Shooting not as well is no excuse for not having good form, but I find it hard to maintain good form when the arrows are flying sideways. But it's a good exercise of mind over wind, (hey, that's kind of neat: turn the "m" over in "mind" and you get "wind"!), so is a worthwhile thing to learn to do.
