I'm not an expert . . .
My thinking -- which may or may not be correct -- is that as the weather gets hotter hogs look for places to wallow and cool off. That means shallow water with a muddy bank in the shade. Look for hog-sized depressions along the shoreline of tanks or ponds, and hog tracks. If you can find a fresh spot where they've been wallowing during the day, throw some corn out and wait for them to come by.
In theory that sounds good, but where I hunt there are literally dozens of small stock tanks spread around, and who knows which ones the hogs will go to on any given day. The one sure requirement is shade, so rule out the ones with no trees along the banks. Other than that, good luck!
