Thank you for saving me some typing! I saw the post earlier, but was lazy. LOL!
Scent carries better in humid conditions because the scent molecules ride on the water molecules. Also, it can be dry and the scent can still carry. How, by riding on dust molecules if they're present.
I'd think the wind wasn't in the direction of the deer when it encountered your camera.
However, I've done pre-season major cutting in the brush to create trails for the deer, then went back the next day to finish up and had large deer kwap right on the trail. I know it was a buck. Go figure.
