If you want to hunt public land in texas, east texas is the best period. There are 4 national forests and all have WMAs in them. The entire 160,000 acre sam houston nat'l forest is also a WMA meaning you can hunt the entire 160,000 acres of it. I think the permit is about $48 to be able to hunt the WMAs and some other public land in texas. I don't know where all the correctional facilities are, but I know theres the one in huntsville, and that would be an excellent location.
