My 2nd UFO sighting, October 1979

This is my second sighting, and I'm not exactly sure of the date, but I do remember it was the second Monday in October, the year 1979, around 10:00pm. I was visiting the home of a friend, about a mile from where I used to live-- my parents' house.  My friend and I were sitting on the driveway, leaning against the garage door talking, and I happened to look up at the sky, when something unusual caught my attention, and we're talking about WAY up in the sky. This huge, I mean really HUGE object was moving across the sky at a very slow speed.  The object was not only enormous in size, but it was white, very bright, and shaped like a dome.  It reminded me of the Captiol dome, yet lying on it's side, with this white foggy type of mist trailing out of it. My friend both sat quietly and stared at this object moving across the sky, and then it disappeared.  Afterward, my friend and I turned to one another in amazement and that was that.
Date may be approximate.  We believe the second Monday in October 1979 may have been the 8th or 9th of October, but we will try to check.  PD
