Date--1/2 Time San Francisco-Seattle 2013 Playoff in San Francisco. Date??? I went out at half time--looked to the South at Cuchara Pass. The soft flood light was higher than the road over the pass, moving into Cuchara Valley. I waited for a back wash sound, but there was absolutely no sound. The movement was very slow, you could not see the outline behind the large light.. The direction changed after 4-5 minutes of it's ascending into the Valley. It then turned up a cut in the mountains toward a couple of mountain lakes, disappearing behind the pines surround my place.I was so aggravated--I had company and she did not hear my call to come out of the house. I thought then--I've seen a UFO--no one else got a look at it...However I went to my best friends the next morning for coffee.. I just casually ask, did you guys see anything unuseal last night. The wife came to a stop--looked at me, "She called me by name, "Did you see that light"?? (She had taken her pups out for a bathroom run)I told her I did, and she was as please as I, to have a witness--her husband did not see it.. This couple and I are retired folks from Texas..That entire day (this happen), there were high fly overs.. This large light could have been a drome, and the Military fly overs-- an exercise. I'm trying as you see to be honest about this.. Do Dromes fly with a bigger than life flood light after it's dark??????????? I don't have a clue.......Understand this--you required a description of the structure.. It was dark--you could not see the structure of the object behind the light!!!!!
