I agree with the above advice, but I also wouldn't sweat the wind direction too much. I'm much more concerned with swirling winds in my area than a "wrong wind." In my area (Middle TN), deer bedding is far less concentrated than on those big midwestern farms you see on TV, so deer can come from anywhere. Sure, I have an idea of preferred bedding areas on the places I hunt, but I see (and kill) more good bucks on a "just off" wind (deer is approaching from 12 o'clock, and the wind is blowing toward 1 or 2 o'clock, not toward 6 o'clock), which I attribute to the fact that mature bucks generally like to walk toward the wind, not walk with it at their back. So, I would just pick the best spot/feed tree/trail you can find and set up wherever you have good concealment and comfort so you're not moving around a bunch. Swirling winds make it tough for any deer to get in bow range without smelling you, while straight-line winds only screw up maybe 30 or 45 degrees of your 360-degree viewing area.
The two exceptions to this suggestion that come to mind are: (1) if you're hunting a buck bed, watering hole, or super-specific spot--make sure the wind isn't blowing straight there; and (2) if you've observed deer approaching from a specific spot consistently, such as moving east on an east/west trail--again, make sure the wind isn't blowing straight there. Hope this helps.
