According to the Texas State Parks web site, Possum Kingdom State Park in Caddo is closed due to the wildfires. One other park is also closed at the moment, and I’m still searching for the name of that one. If you know which one it is, please leave a comment.
It would be helpful if the state parks’ web master would post this info on their home page. Meanwhile, if you’re considering camping any time soon or visiting any of the state parks in the fire-prone areas, be sure to call ahead.
