You can hunt in Seguin with Randy. I have hunted with him before and he has state of the art optics and weapons. IIRC they were suppressed .44 mag rifles with hand loaded sub sonic ammo. You could hear the rounds smack the piggies. They do lots of feeders and have lots of different places to hunt depending on the wind. nighthogsdotcom
With this group you will get quality over quantity if what you are looking for are large hogs. Usually may get one or two per night per person.

This other group out of Columbus is not fully guided like Night Hogs, more of a do it yourself deal. boars nest hunts is in Columbus TX. I hunted there with a group of 4 and we shot about a dozen hogs. This was about 4 years ago. 1 hunter didn't even shoot one and another went to bed early with 2. me and another guy shot the other 10 or so.

The best areas for hogs in my opinion are going to be east, northeast, southeast and south TX. Central, north and west tend to be drier with less cover for the hogs.
