Find a pond or water hole that the hogs are using a lot. Builda tree stand overlooking that water hole and wait.
Exactly what I was going to tell you to do. Your bait site needs to be right on the edge of the water too. Doesn't matter if the corns gets wet. They like it sour just as much and that keeps the squirrels from eating it all up first. Coons will eat sour corn though. Just make sure you feeder is throwing enough when the hogs do find it.
