Summary : Father and son driving west on Hiway 6, around 6 pm. Glowing object stationary for 6 to 7 minutes. Object turns on end, then turns to show triangle shape with bright light on one end then disappears instantly to the west.I was driving down Hiway 6 heading to Holstein with my son. We noticed a very bright light ahead in the west. It was about 6:05pm and the sun had gone down, but the sky was orange and clear with no clouds. We noticed that the object was not moving, there were two jets farther west behind the object, which I used to judge size. The object was very large and was stationary for 6 to 7 minutes. As we turned south off of Hiway 6 on to the junction road that leads to Holstein we kept our eye on the object, which seem to be turning in place on end, to give it a long shape that look like a long glowing cylinder. Then the object turned again and we could see that it was a triangle shaped object, with a very bright light on one of the points. We were head for the next gravel intersection road to turn west to watch the object. We turned right and while we were watching the object, it seemed to dim a bit, then it was gone instantly. We proceeded down the road further, but there was no sign of anything. This object seemed to be very large and was definitley triangle shaped from our last view of it. It was very impressive. It was not dark out yet, and the sky was clear, so there is no doubt that we saw something very unusual.
