4 white lights circling counter-clockwise coming together as one light separating again and repeating patternI was driving south thru Iowa at around 11:45pm on 7-28-12 and saw in a field to the east of Interstate 35 south just outside a town called Cummings 4 white lights moving in a counter-clock wise motion then coming together at a focal point then separating again to spin again there was a thunderstorm to the south and the only reason I could see the lights is because there were some low lying clouds that the lights we reflecting on it looked like it was coming from the ground but I could not see the point of origin or tell how far away it was I did not see any buildings or lights on the ground around it. It seemed to be coming out of a field. I drove for what had to have been 30-45 minutes and the lights continued until I eventually passed into the thunderstorm and could not see the lights anymore.
