I did the Calcasieu River about 14 years ago, before they changed the sandbar camping law (2008?) A friend of mine owns one of the many small canoe outfitters in area, and in return for an afternoon helping him schlep canoes, he let me use one, put me in at the Hwy112 bridge, and I drifted for two overnights and a couple days down to Hwy 190, where he took me out. Great water back then, though one section was full of drunken day trippers for a couple miles before their takeout. Wouldn't do it again today... nowhere to camp without trespassing, and the crowd is much rougher. I've heard from a local sheriff friend that the cops keep a closer eye on it than they should have to... sad.
You live within a couple hours of the Neches... It's a nice river, for the South... pretty clean, and the stretch from Steinhagen Lake down to Evadale is nice, going through the Big Thicket National Forest as it does... about a 4-5 day 3-4 overnight trip, depending on flow. The Sabine is nice too, but nowhere to camp between the reservoir and the Gulf now... all private land. Takes about 4-5 days to run that whole length, according to my friend (who used to offer a shuttle for that trip.)
I've recently re-discovered Toledo Bend. The entire southwestern corner is national forest, maintained by Texas (vs LA), and they do a really nice job of it... controlled burns, decent roads (for dirt, that is), relatively well-maintained since they have a budget and a thriving economy.
