With today's near borderline outrageous marketing promotions and asking prices for "bottled gold" in one ounce portions, it's a wonder why I haven't heard of more hunters doing something simple, effective, and extremely economical. The next deer you kill, when gutting it, empty the bladder!! Chances are you might have tons of empty amber bottles which once contained Tink's 69, Code Blue, or some other scent-fill em up with some of your own "home brew" and save it for your next hunt. Oftentimes, especially if the bladder is both full and intact, you might can salvage up to 12 ounces if not more of doe or buck urine. When you consider some companies like Code Blue will sell their stuff for $12.99 where I am from, that adds up to over $150 worth of free product. Also, take the time to cut the tarsal glands out of your bucks, no matter whether it was an inferior buck that someone else shot, or a monster dominant buck. The several deer processors where I am from will let me come in there and take all the bladders I want, for free. They are just going to end up in the trash, anyways.
