I am not in the Dallas area, but I have been meaning to take a trip there and explore the state parks around that area. I will definitely take note of your recommendation. Looks wonderful!
In Texas, I have personally only been to the state parks near Houston, Galveston, Austin, El Paso, and San Antonio.
This picture is from Brazos Bend near Houston. Warning: they have alligators (large ones at that).
