Watkins vanilla extract the best curiosity sent I have ever seen. Rub a little on your boots walk to your stand and drop a cotton ball with some on it and the deer will come in. I have had deer walk right in the way i did and lick the steps to my stand now that only happened once but it was still cool to see.
And the best part is if you or your wife like to bake the stuff is awesome.
