Texas, the new Florida

The FBI have been investigating this for decades and still don't have an answer. All they say is that foxes and possums normally eat the tender areas of recently dead cattle. No explanation as to why the area is so sanitized and the carcasses drained of blood. I would like someone to bring forward a sensible explanation. It's not like crop circles, where you can prove people are cranking you. Just give me an explanation that makes sense, that's all I ask.
