January camping halfway between Dallas and Baton Rouge

Our son is going to run the marathon in Baton Rouge the Sunday before MLK day and we are thinking about taking the AS down on the long weekend. Rather than do the entire 6 hour drive (I just came off the 6 hour drive from Village Creek SP, ARK and still have that memory) to BR, would like to find either a COE or State Park halfway, probably an hour east of Shreveport so that we could knockout half the drive on Friday afternoon. Any suggestions from Louisiana Streamers? Also any suggestions for camping near Baton Rouge?



Thanks

Dana
