Never hurts to try. Hack off a 2 to 3 foot piece of grape vine that is about as big around as your thumb or a little bigger and add it to your set-up. The sap smell and taste will attract interested parties and the sticky sap will help hold the natural deer scent. The deer "should" take care of the rest. Don't be afraid to put up several and let the deer tell you which one they like the most. A difference of 10 yards can make a difference sometimes. Post up some pics, hang a cam and good luck!
