Can you hunt at night there? In June because of the heat, the hogs will be moving more at night.

Try taking an old ice chest, one you don't care about losing.

Pour a bag of corn in the ice chest and add enough water just to come up to the top of the corn, close the lid and duct tape the lid around all 4 edges. Let that sit in your ice chest for a week or so, and keep it in the sun. Now be careful becaust that corn is now sour and will smell like crap.

Spread that over an area that you have found recent hog signs and hunt it at night.

Hope this helps! Good luck!
