I've heard a few other stories about people seeing UFOs from North Austin to just south of Waco. I don't remember the details as it's been some time ago but remember several people seeing one hovering over I-35
I was out partying in that area when I was in college. MIddle of nowhere, deep in hill country woods, rest stop type place, the type of dumb things you do when you're young. We were all #*$#* up.
We saw a light coming at us, it was the wierdest thing. Best way to describe it is it was getting closer, but not getting larger. We got freaked out and left. We were also worried it was some type of security because we were next to a large high fenced in area. Anyways, like I said, we were all blitzed so I take it with a grain of salt, but I can easily see some of those desolate highways in Texas prime for UFO stories.
Especially if you go west towards El Paso or south towards Laredo. NOTHING on the road for miles.
