In Texas, only need out of state general license. Feral hogs considered vermin and have no closed season or State limits, only landowner limits. Javelina vary from county to county, but most counties south of San Antonio have no closed season. Bag limits vary. Info at Texas Parks & Wildlife online. On javelina, either have a guide field dress them or have a local show you how. They have a scent gland to be dealt with. If not done properly you will ruin the carcass, and they are pretty tasty. The terrain is much like areas of South Africa and Australia. If you are not accustomed to moving through snake country, have the locals show you. Knowing where and how to walk is far more effective than all the leggings and snake loads in the world.
