I’ve had numerous deer show up while ascending or descending in a climbing tree stand, which is obviously quite loud in a quiet forest. How about deer being attracted to chainsaws when felling trees? When in the tractor or ATV most deer and turkey couldn’t care less. Point being, many scents and sounds might seem like they’d scare every animal for miles when in fact the game has never had a negative experience to associate those smells and sounds with danger.
I mainly still hunt deer and have stalked within 10-20 yards countless times. It’s this method of hunting which has taught me what you usually can and cannot get away with.
