Sometime in the Early 2000's. 2002 or so, I was in Grad School at MSU-Bozeman. I was planning on meeting some friends in Pinedale, WY one Friday evening so we could go backpacking in the Wind Rivers. They were headed up from Utah, and I was headed down from Bozeman. I got stuck at work and got a little later start then I had hoped, but not by a lot. It got dark around the time I hit Idaho, but it was a full moon out that night. I had a hard turn towards the south on the highway just north of Driggs Idaho, when I noticed something above me against the mountains. Slowed down and had my head cranked out the window and could clearly see an aircraft, but it didn't seem like it was moving very fast. At least not fast enough to stay in the air. So I pulled over and took a step out of my truck, and watched this thing cruise over me at what seemed like a very low elevation. 100 or 200 feet or so. It moved gradually right over me, and never made a sound. I have an image stuck in my head of what appeared to be a Black double edged knife blade, or tip of a sword. If it hadn't been a full moon, I'm not sure I would have seen it. I just remember the moon light reflecting off this dull black aircraft. Then as it moved past me, it accelerated at the speed of light and became just a light in the distance. I got back in and kept driving and could still see this weird light WAY off in the distance just moving along.
I crested over the pass to drop down into Jackson Wy and there were huge fires in the area. Camps full of fire crews right off the road. It was slow going through there, but traffic wasn't stopped or blocked at all. Got up on the plateau between Jackson and Pinedale, and realized I was running really late. It was a full Moon, and it felt like I could see Everything in that sagebrush flat. I was Speeding along pretty good for the majority of that 70 mile stretch trying to make up time. I got to Pinedale, and met my friends at the gas station. They were laid out in the truck bed in their sleeping bags fast asleep. Turns out I was about 4 hours late!
Now mind you this was back in the days of printing MapQuest directions and I did get a late start, but not that late. It did have a quick stop to awe at some unidentified aircraft, and had a slow section through the fire camp, but Not 4-hours worth.
Near as I can tell, what I saw looked ALOT like the front end of the Blackbird. I have less recollection of what the tail end looked like. But it never made a sound, seemed to hover and then instantaneously accelerate. If I had to guess, whatever it was, was in the area checking out the fires.
