The wind is my friend. A 15 mph wind means nothing to me except I can get by with more movement and deer are less likely hear me draw or to spook after my arrow zips through their lungs. I think the wind has a bigger effect on the hunter than the deer. I do know that I have killed 3 deer this year when the wind was blowing 20 mph with gusts up to 30 mph and 2 more when the wind was blowing at least 15 mph, and that is in a combination of 3 different states. I wish you guys would try to keep this a secret though because I don't think the deer in Illinois, Arkansas, or Mississippi know they aren't suppose to eat when the wind blows
