This event was seen my many-the objects were clear and distinct-and moved independent of each other-if left who all saw this overwhelmedMyself and 6 others were traveling south on I-25, in southern Colorado. We were traveling in 3 seperate vehicles and traveling betwwen 10 -15 minutes apart. We noticed some lights moving strangely in the sky, and as we watched them we were going up a very steep hill on I-25 and as we came to the crest of the hill, and to the point where we could see the valley below, we were presented with a scene that brought us to a stop in the middle of the road. It was like a scene from a movie,the valley was filled with light and ships-they were at 500-600 feet off the ground. There were at least 8 vehicles pulled off the road that we had seen, with people standing out and looking up at the craft in the sky. We were between Rye Colorado and Walsenburg, Colorado. The two main objects were bigger than the other objects, and stayed centralised to the others as the others moved and enteracted with each other, almost as if playing. They moved in and out of the range-as we were in front of the front range of the Wet mountains. Two helicopters and two fighters approached from the direction of Norad or maybe Ft.Collins. The helicopters and the jets stayed mainly on the perimeter of the objects, which at times were in an area of the sky, of about a mile. The two main objects were orangest and the smaller ones more yellow. The objects were moving south at a very slow rate and seemed totally unconcerned with the helicopters or the jets. The smaller objects did manuvers unlike anything we had ever even imagined and the seemed to glow and blink at each other as if enteracting. They moved at times together and then other times apart. We were all so stunned we realised we were holding hands and just asking each other if this was somekind of beginning or maybe and end.
