Dim triangle of lights, high speed, low altitude but no noise over Boulder, CO 10/17/2009 10pm

Three small, dim, whitish lights forming a triangle flying at a high rate of speed, low altitude towards the northwest, just on the plains side of the foothills on the far north side of boulder. Three of the four of us in our group saw it and all agreed it was too fast and too low to not hear any associated jet noise. No normal aircraft signal lights were seen.
