A11en, I'm not sure where you hunt, but where I do, we like to hang a deer for aging. So in our case we field dress our deer. Granted, during early bow season, we often don't have that option. So we generally quarter and "age" in the beer fridge. Even then I still field dress my deer.

As far as placement of the pile, we generally drag them off of main corridors. We also see that most piles are gone within a day or two due to coyotes and other scavengers. Regarding human scent left at the dressing site, I can't say for sure. My assumption is that the pile in and of itself probably outweighs most of the human scent.

I've seen plenty of studies showing various scents, human and otherwise that don't affect deer movement or patterns after time - say 24 hours.
