been doing it for years. it works. a friend of mine was getting pissed off that this guy had put his lock on stand fifty yards from his. there was a scrape between the two stands one day and my buddy decided to piss in it when he was leaving. thinking f%$k this guy for being so ignorant. when he returned for an evening hunt that weekend the guy was dressing out a nice buck and explaining how the buck came into the scrape. i' ve been doing it ever since. almost all of the scrapes are torn up when i return. give it a try and see what happens. good luck to all.
