I was driving west along the turnpike and saw what at first appeared to be two stars. As I watched, I noticed that they moved slightly, and always with each other. I also noticed that there appeared to be a cigar shaped mass between them. I stopped to observe more closely, and saw them very distinctly move to the right. (North) as an airplane passed from the south. By this time I had awakened my codriver, who remembered witnessing something similar once before. We drove on, keeping sight of the object until it finally disappeared behind the mountains. During this time i drove approximately 75 miles and the object never got noticeably closer or farther away.
