RE: Deer Question
Same. I have camo, try not to fart and I have been successful without all those marketing gizmos and gadgets. I have even gone straight from work in jeans and a shirt to my stand and have come out with deer. I don't think it matters much as long as you have the right background, concealed stand location, etc.
My buddy even chews tobacco and he's more successful than I am. It's partially luck out there and those cover scent products might work, but not worth my hard earned money!
