yeah Big Tex i found alot, but trying to see for any special recipies... never hurts to ask
I understand your point. There is no magic formula that will work everywhere.
Lets approach this from another perspective. Some people like rare stakes some people well done. If I was a hog I would be used to what is available to me, nature provided or area provided and I would not touch junk food.
Here is what you can do if you will hunt that area for more then just one time. Make sour corn, jello corn, diesel corn and all formulas you can find including plain corn. Bait various locations as far apart as possible. Next morning you will have answer what got hit. People swear by commercial attractant and other formulas. I do not believe corporate BS and commercialism. It's just like feeding dog with potatoes while dogs do not have enzyme to digest starch. Just use common sense and be patient.
