Y'all are funny... I'm in SC but my heart is in South Texas. We have have a big hog problem as well!!
They are just so smart around here,,, you kill one or two and then you're done at that hunting spot... they will move on or come only at night.
I was actually turkey scouting this morning... but the field I'm seeing all the birds in is rooted to kingdom come. So I took the .243 with me and shot him right at dawn.
