I hunted the Webster area last year and was wondering if the yellow WIA signs were different from the normal white ones. They seemed to be around standing corn? The legend from the 2008 Atlas showed a blue or purple border around WIAs that could not be hunted while the crop was still standing. Some of the WIAs from the Atlas had gray diagonal lines through them and seemed to be in the area of the yellow WIA signs. Any ideas about the yellow signs?
