Call me CRAZY, but I'm a fanatic about SCENT control, and I pay a little attention to the wind, but I've killed many deer that were downwind, including my biggest buck, and a herd matriarch that "had it coming." I don't honestly remember being busted by anything by my own stupidity of moving, or dumbluck that I got busted moving by an animal I didn't know was there. I use X-scent or an alike Silver Ion base layers, and spray off with a little scent killer and use just a little BUCK URINE for my cover, rather than doe urine or coon urine or whatever. It's yielded good results for me the past few seasons thus far.
