bought a book online to pass the time and it had some really cool tips and tactics in it that I never heard of or used but seemed pretty promising,has anybody ever used the water bottle and grunt call combo to draw in call shy deer?the author uses the water bottle to pour out to sound like a deer urinating in an area that he is blind calling in and says that more times than not that it draws in even the most stubborn of bucks.if anybodies interested the book is called"deer hunting for the clueless"and I got it online for my computer from amazon.
