Haha thats funny.... I don't understand how anyone can think that all pee is the same, degrades to all the same, yadayada ya. All aminimals use pee as communication, marking territories, sending bredding messages, ect every day..... For those that use this method it would be interesting to see if they've killed any big mature deer with these methods. I always here about it working and what not but never any pictures of these big mature deer they claim it works on. Old degraded human pee may not scare deer and "work" but how about that fresh stuff..... I think I'll save the real deer urine for my scrapes and my bottle in my pack . WCL
