I lived in texas for a few years and my advice is to drive down and hunt public lands.
My step son used to shoot them at the end of our street in red river county. Pigs are not magical elusive creatures. If you want to hunt a ranch or use a guide at least find one who is reputable..
Pigs aren't lions tigers or bears you have nothing to fear but tall tales. They aren't aggressive and generally run like a mofo unless trapped with no way out.
