I like your idea sqiggy. I'm just curious how the corn dries out after you mist it and put it in the barrel. I would be concerned about mildew on the corn.
Works best if you have 2 people. One pouring the corn in and another giving a "spritz". If by yourself, just pour a little corn and a quick spritz. All you want to do is give the corn an odor. Never had any to mildew. Then, when you get ready to hunt, put some hand corn out and spray it down good.
I started using vanilla years ago, especially when I hunted on the TPWD draw hunts where you only had a couple days to hunt. Once I found a promising location, I would take a whole bottle and slosh it all around. By the next day, had deer everywhere around me.
All that other stuff, deer cane, comere deer, etc. is all gimmicks.
