Do you have a better photo of the tail or a closer photo of the head? The scales on the head, the overall pattern and color look like a Crotalus scutulatus to me - this is definitely a weird pattern and color for a C. atrox. Plus it has the typical two interocular head scales like a C. scutulatus.

Atrox, I also first thought it might have been C.Scutulatus, but didn't think they got to that part of Texas?? I agree that further pictures would also help greatly in this instance as the lighting and shadows in particular make it hard to see the tail and features. That said I would have to bow to your knowledge on this species :)

I've added two more photos. Hope they help. I was under the impression that Crotalus scutulatus didn't come this far east. The guide books only show them in west Texas.
