Take an old pill bottle like you get from the pharmacy, some 1/8 inch thick cotton twine, and a J-hook. Melt a hole in the lid of the pill bottle just big enough for the twine to fit thru. Run the end of the twine thru and tie the end in a knot. Take the j-hook and file off the point and the barb. Tie it onto the other end of the twine. Now just put in your favorite scent. When ya get to the woods just pull the string and hang the bottle from a limb. Also works good if ya make several and put them in a triangular pattern around your stand. Helps to mask your scent as well as lure the deer in.
