I was traveling home from a work related site visit and relishing in deep thought. At the moment, I had been thinking are ufos and et's real. As I continued to think on this, my attention was drawn to the east bound side of the highway. I noticed something that looked like a cloud. I thought a cloud? What? Why would a cloud be that low? Clouds don't hover that low. Then realized it was a cloudless beautiful day. There were no other clouds anywhere near me except miles and miles in the upper atmosphere. Next I realized the cloud was actually moving. Silently floating above the power lines about twenty to thirty feet. It was shaped like a potato. As we passed each other,I thought that is the strangest thing I had ever seen. Is this real? I slowed my car to stop and ask other drivers if they saw it too. No one appeared to be stopping. They kept going as though they saw nothing. I began to wonder if that was for me since I had asked the question. No one was in the car but me. I continued to watch through the rear view mirror. It continued to follow the highway like cars traveling on the road and it continued to follow the highway as far as I could tell when it reached a bend in the road. I was so excited. I saw my first ufo. I told several family members and my immediate family. No one was really interested except my oldest child who has seen his own ufos. Some I told I believe were actually a little scared. I still think about to this day, but never saw anything again.
