Honestly, save your money and your time. Don't stink up the woods with artificle junk. HUNT the deer. Learn their patterns. Find the food. Don't go stinking up the place. Mock scrapes were invented by someone trying to sell you a bottle of imitation junk supposedly designed to fool the smartest nose in the woods. Guess who wins? Exactly, the guy selling the cow pee in a bottle. Go hunting.... forget the fooling business. Go Stinky Free as you can..
