​We live in the Hill Country and my teenage son and I just got to the top of our street to leave neighborhood. I spotted a silver object moving in the sky. The sun was gleaming on it more than any planes that pass over. I didn't say anything and watched it as I drove. I thought there was no way it was a plane as it was moving way too quickly, no sign of wings and it changed altitude rather quickly up and down once, then a little to the east and then disappeared. It was there one second and gone the next. I hadn't said anything and I'm looking all over the very clear sky (no clouds) to find it. My son says, "It just up and disappeared!" I said, "you saw it too" He said "yes,and it just disappeared." We both decided it was not plane. He told me that he was watching it closely and it was a circular metal structure. He said it was no plane. (And my kid thinks I'm crazy for believing in UFO's.) Not anymore.
