I feel embarassed just to say I tried it one time 2 years ago. Buy cheap peanut butter at wally world. Paint it flat black if you don't want other people to see where your feedin deer (remember you can't do this during the season) to bring them in the area. Then just tie it to a tree and cut a 2-3" hole in the bottom so the deer gotta work to get to it. It cost less than a dollar, last weeks, and works better than anything on the "deer market." Give it a try
