I'm not sure how it works in Texas, but here in Florida, land owners have come to realize that the wild hogs on their property are something of a commodity. Don't get me wrong; they want to get rid of/control them, but they have learned that they can lease the hunting or trapping rights and pocket some extra cash. Even then, they want hunters that they know and trust before they give them keys to the gate. I have spent years cultivating trapping/hunting priveledges on several pieces of property. I work on much of this land and I have gained the trust of the owners by helping out in ways beyond what my work calls for. ie: reporting poachers, repairing fences, supplemental feeding of deer and turkey with no expectation of my hunting priveledges being extended to these species. Clearing downed trees, digging water holes, planting food plots, stocking ponds and on and on. As a result, even on land that is leased out to others, some owners defer to me to oversee any and all hunting/fishing on their property.
I can only suggest that if you are looking for private land to hunt on, offer your labor in exchange for hunting priveledges. Then get a clear understanding from the owner of what you may and may not do on his land (in writing if possible) and never overstep the priveledges extended to you.
I caught a guy fishing/trespassing on a friends property last Saturday. Said he had permission from the owners kid. He didn't know who cut the lock off the gate. He left the property in handcuffs in the back of a patrol cruiser. Seems he had permission in the past but had been told not to come back for having brought a bunch of guests and leaving trash around the pond.
