I saw a hovering metallic grey saucer shaped disk hovering over the South Gate Golf courseI was heading south on interstate I-15 I had just passed the Bluff St. Exit. Over the South Gate Golf course there was a dark metallic grey saucer object hovering over the golf course. It appeared as if the object did not have any lights. It was about 1 and ½ size of the moon in the sky. If it had lights they were very dim and along the outer ring of the craft. It could have been the reflection of the moon on its shiny surface too I could not tell. It slowly dropped in elevation as it moved north. It started to bank to the East at that same moment I had to take my eye off of the object because I was driving. I looked away for only a short second and when I looked back the object had vanished. It was not close to any horizon or hill so it could not have just disappeared behind anything. It just disappeared.((NUFORC Note: We spoke via telephone with this witness, and he seemed to us to be unusually eloquent, objective, and sober-minded. We suspect that he is an excellent witness. PD))
