I was driving home to California from Idaho on the freeway at about 2am when outside of Lovelock, Nevada I observed an unusally round very bright object in the sky to my right above the mountain top. The light was not starlike. It did not sparkle. There was just something odd about it. I passed an 18 wheeler and that bright light was still there.Then all of a sudden, it took off to the right leaving a very bright trail, zig zagged and dived liked it was out of control then disappeared. The sky was very light on the desert that night and it appeared to just disapear. There were two exits which followed and Toulon air base was one of them. I keep thinking about it......
