I met a girl that saved her, well, items in the freezer and used them as boot drags during deer season. According to both her and her husband, they said it never failed to bring the bucks in.
I've always considered myself a serious,legal hunter. Having utilized urine from bucks or estrus does, tarsal glands as well as relocating fresh deer droppings to equate them into my hunting scenario. Have even used the same from goats as well in deer hunting with success...
...but there are limits to the extent I'd go for a monster buck.
For the record...this would be above my limits.
