Calls and rattling do work. I've been a avid bowhunter for 23 years and can honestly say that i would have never brought in the bucks i have from just sitting in the stand. With a drought of property to hunt i've settled for small parcels that require calls and rattling to attract the bucks from long range to my area(during pre and rut only) Have i screwed myself by calling and rattling (yes) but for the times I did it right there was success. I use deer urine for mainly scent cover. Figure it this way... If its authentic whitetail urine it will do you no harm and only benefit you because it symbolizes traffic. I've called bucks in from hundreds of yards away that had no intentions of heading my way. Use a call and rattle but like everything in life use discretion.
