My dad found this one, along with a Bonham. He lives an hour away from me, so I'll put a pic up later.
After the sifting, my dad and I went to friend's house in Badera. He lives about thirty feet from the Sabinal river and let me poke around his property. I found this while checking on a pile of dirt. Turns out the dirt came from a crew that cleans the ditches along the side of the road.
