I used to drag a old piece of t shirt with estrous scent, off to the side of me while walking in, then tie it to something off the ground, some 20 yards or so down wind before I get to my stand or blind. I want to draw them near, but not draw attention directly to me. I haven't done that in some time though. I may do that next time out, now that the rut is about on. I just so happen to have a bunch of 6 ft bamboo stakes to help with that!
I know guys who put scent all over their boots or strap a scent pad on. I feel that leads their nose directly to your stand. If there is mud anywhere nearby when I am on my way in, I make sure I get some of that on my boots. I'd rather smell local.
