I'll put it this way... I'm heading out this afternoon after a buck I've got on trail cam that's got a huge sticker coming off his right G2; I've always wanted a "sticker" buck. I saw exactly where he came out two nights ago, and I'll be set up there by 4 this afternoon because I've gota perfect North wind to do so.
If the wind was even blowing ONE mile per hour South this afternoon, I would NOT be hanging there. So I guess there's your answer... from at least one die-hard wind player.
