I use Deer urine 100% of my time hunting ...why wouldnt you ? Just another tool to use. I have gone to using Fresh Deer Urine and it has made a good thing even better. Is deer urine a 100% effective ...NO But I have shot most of my bucks with there nose sticking in my wicks or scrapes that I have made.
I am using StoneyCreeks products
