I hunt to get out of the house, if I shoot something that's a bonus. If I just want meat I can go to the grocery store. I disagree that if you don't bring home meat then you might as well have stayed home, this isn't the 1840s.

As I've said, I'm fairly new to hunting, and been somewhat successful without considering wind. While hog hunting, the only ones I've missed are the ones where I couldn't get a shot off in time, so my very limited experience is that you need a solid rest, a confortable position so you can stay ready for hours at a time, and smart shooting lanes. Hogs do seem to be able to smeel, I've seen one (friend's personal video) where the hog walks up to the point my friend approached to get into his tree stand, and at exactly the point where he walked (within 6 inches) the hog does a 180 and bolts. His guess was that the hog smelled the rubber from his clean new sneakers. So we both are careful to wear weathered footware and get them real dirty before hiking to the stand.

If I owned land and were setting up blinds and had time to think about it, I might think about prevailing winds. But most of my hunting is Texas Parks and Wildlife hunts where they assign you a blind, drop you off there in a truck, and wave goodbye. The only thing under your control is the shooting (solid rest, always ready). Either a deer/hog walks by or it doesn't. Wind and moon phases are not under your control.

Here's the 2nd (and last) deer I've shot.
