I'll go through the scent reduction routine if I'm hunting out of a stand but if I'm spot and stalk hunting in the mountains (like usual) scent control is impossible so you've got to pay attention to the wind and pray it doesn't get fickle on you. Same goes for bear hunting, you can throw scent control out the window because you just can't stop them from smelling you unless you stay downwind. Comparing a bear's nose to a deer's is like comparing an eagle's eyes to a blind man. You can maybe fool that deer's nose sometimes with scent control but you better still be paying attention to the wind.
