I think I would agree with nyslowhand. I live in an area of fruit orchards and hardwoods. Deer become accustomed to the activities of humans and the sounds of machinery and very often are not alarmed by human scent unless some movement seems directed toward them. They then run a short distance to see if they are being pursued and if not, stop and resume what they were doing.
In the woods I use a ground blind and in the last couple of years have had deer walk to within 10 yards of the blind. However last year I got busted by a very large mature buck right after first light. I still don't know if it was my scent or slight movement inside the blind.
