NASA,
While I agree with you overall, You're providing a lot of cut and dried answers relating to animals that are, if nothing else, unpredictable. I agree that misting won't cover your scent and it won't cause them to lose their fear of man, but it can be an attractant (just ask any trapper). When I first started calling coyotes, I pulled out all the stops, trying everything I could all at once in order to gain any possible advantage. Over time, I've discarded most of them and am at least as successful.
Although, like Arcticfox, better callers than me swear by misting, I've never hunted with them, I suspect they prefer different terrain and I know their techniques are a bit different. As with shooting, I prefer to keep it simple and stick with the fundementals: Analyze the terrain, work the wind to your best advantage, take any luck you can get, shoot straight, analyze what did or didn't happen on a stand and hunt all day. - John
