I'm a cross country trucker. One evening after midnight on a cool Sept night I was driving west on interstate 10 out of Van Horn Texas.As I topped a hill, I saw a bright light off in the distance towards what I thought maybe El Paso Tx. Ahead was a rest area so I pulled into it and parked. As I watched the light it came closer and closer but not fast. It was gradual and steady. It was hard to tell how far it was but at first I thought it was a star but as it came closer it was about the size of a golf ball or a full moon. As I watched it , it seemed to stop. Then after a few seconds it just shot south so fast it made me scared and feel like I didn't even really see anything. I climbed back in my truck and got on the CB radio and asked if anyone saw that light. After a moment of silence I heard a voice say " I did". We went to a channel other than 19 and both told the same story to each other. I felt somewhat relieved knowing I wasn't the only one. Since then I've only told my wife. I still remember it like it happened today. I'll never forget it.
