I was returning home and traveling West on US Highway 190 in my truck. As I was approaching Nolanville Hill to start my decent down the highway, I noticed a large, bright, orange, amber, red glowing light. It was shaped like an egg, with the small end at the top and seemed to be the size of a Volkswagon Beetle. It followed my truck across the top of the hill and dropped down to a lower level and continued to almost track my movement down the road. I continued to watch it closely and pulled to the side of the road shoulder, I had both windows open and I shut off my truck. There was no noise.. I then exited my truck to retrieve a pair of binoculars from my truck tool box. All the while the egg shaped craft was glowing and there was a solid outline of the egg, but the inside was like flowing lava, with a liquid fire like flame or pulsing boiling almost alive movement of what I call lava light. I found my binocs and put was raising to put them to my eyes... and that thing left out of there in a way that still sends chills up my spine... It was like warp speed X 10!! I traveled in a straight line trajectory to the NW. There is nothing on the face of this Earth that can move like that! There is not a speed I can even equate to it. And it was intelligent and observing me. It did not want me getting a closer look. I marked the time and returned home and called the local Skylark Airport and ask if there had been any unusual activity reported at that time and they said no, and nothing on radar in that area. I will say that it has changed my life and my belief system FOREVER.
