UFO spotted over Garrison, Minnesota.On the way home from a gas station, I looked up into the sky and saw two craft in formation that had lights on them in a triangle shape. I first thought they were C-17's or C-4's but they were moving too slow to be of those nor did they have any strobe lights! ALL military and non-military aircraft, HAVE to have strobe lights. The crafts were located just above Borden Lake in Garrison, Minnesota traveling south east. As far as the objects themselves go, I could not get a accurate discription on the shape of the crafts besides the lights on them, from what I could see they seemed to be cresent shaped. Once again, it was dark out and I could not get a accurate view on the shape of the hull of both craft.
