I'd definitely say that if deer are blowing consistently as you're in your stand, you have an odor problem (now, don't take that personal!
) Most places I put stands are travel corridors or funnels. Because you never really know what direction deer are going to approach from (especially during the pre rut and rut) I do not worry about wind direction. I do worry, all the time, about scent control, however.
This morning I hunted a stand that's normally an excellent location. Seven deer seen, including two (small) bucks. At one time or another deer were all around this stand (ladder stand, 15') and no deer showed signs of scenting me. Deer at 20 yards to my front and two more passed 5 yards to the rear of my stand. When deer are that close, I'll even try to pull my scent-lok hoodie over my mouth to try and hide my stinky breath too.
Everyone has their own methods and planning sequences. But, I truly believe they can all benefit from extra care taken in the "stink" department though. I never wear clothes to deer hunt, that have been worn elsewhere, except en-route to hunt. And, I always fear getting busted in a stand, as I believe deer have a good sense for remembering that, at least sometimes.
Of course, we all know of people and times when planning for a hunt was flawed, but the outcome was still great. You just never know for sure, one of the great things about hunting. As I've said, I simply think it's a good thing to hedge our bets and take care of things we can
control. Unfortunately, the wind ain't one of those.
