Try Mesquite Bowhunting. It is a short drive just west of San Antonio. I haven't hunted it myself, but I know some serious hog hunters that have and they say the place is incredible for hogs. I think the web site is
www.mesquitebowhunting.com. Don't expect too much from their web site, it's sort of plain. If you end up going, I'd appreciate it if you sent me an e-mail telling me what you thought of the place. I'm thinking about taking a trip myself. Good luck.
