I've seen that and we have nothing like it in N Central Texas.One of my hunting campaneros has a ranch near Austwell-in fact it joins the Aransas Pass Wildlife Refuge - and much of it looks like what I see up around James' place from I-45.
That's what I'm talkin' about!!!!!! Ol' rancher I know said as a young man he worked on a ranch at Gause Tx. south of Hearne Tx. Said he ruined a levi dungaree jacket first day out in that stuff on horseback. The stuff is bad.
Speaking of Gause. It lies close to one of the islands of grass in the Monte. West of Bryan/ College Station. A local geographical landmark there is a hill known as Sugarloaf. Many think this may be the location of one of the Native villages of "Tortuga" on the Camino Real.....
