Around here, Good luck gettin a coyote to come into an open field for any reason during the daylight!!

and by putting the wind at your back you are forcing them to come into gun range to smell the sound source. But now your inviting them to come take a sniff and they will probably be gone before you ever see them. Isn't it more logical to have the wind in your face so you will spot them when they begin to respond, and then it's just as simple as shooting them BEFORE they wind you rather than Making them wind you??
