I do just about everything I can to minimize me disturbing the area. So breaking up the contour, hiding my face (eyes and faces looking at you mean predators), and try to match camo to where I live and when I hunt. Not just for deer but also the birds, squirrels, etc because if they are acting scared they might alert a deer or at least put them on edge.
Also it might I can see wild life a little more naturally then if I was just screaming "human here!" Visually, audibly or through smell.
I was way too excited for US too. Like good on the UK starting to straighten out but damn I wish it was us
