I'm going to have to delve deeper into the whole issue. Apparently there's also a small hand full of "state parks" where firearms are not allowed either such as Aransas Pass.
They could restrict hunting arms but I don't think they can prohibit handguns carried under a CHL.
I was duck hunting with a guide who was being harassed by the local game warden. He would not let anyone have a pistol or rifle (even though pig was in season and available where we were hunting) because of the restriction on having lead shot when hunting waterfowl. Seems that he also may have been guiding on public land when and where it was prohibited to do so- but I didn't know that until after the sun was up and the Ducks were dead.
