I saw a rectangular football field size object, covered underneath with dozens of colorful lights, gliding over the trees and road.

It was approximately 2:00 am in the morning on a summer's night, and I was driving home from a date.  At one particular point, I was the only car on the road, and it was pitch black (no street lights), and I was driving past a farm field with woods surrounding both sides of the road.  It was then that I noticed a large rectangular object hovering over the trees to my right and slowly starting to move across the sky in a northeastern direction.  This object was completely lit with many colorful lights on it's underside.  I remember being completely aware of what I saw, and knew at the time that it certainly could not have an airplane, because of it's shape and many, many underlying lights.  It was completely rectangular, approximately the size of a football field.  I also remember thinking, "I can't believe there aren't any other cars on the road to witness this with me."  Although I thought that was strange that I was alone to see this, I also felt very certain that I was supposed to see this. It's as if it waited for a car to come by so it could show itself.   As it slowly crossed over the road ahead of me and headed toward the trees, it disappeared with no sound.  I felt this was a very deliberate incident.  Like others, I was looking for news stories about this occurance  for the next several days, even mentioning it and questioning others about it.  However, there were no other sightings or news reports that I could find.
Witness indicates that the date of the event is approximate.  PD
