We were traveling west just outside of Assumption, IL going towards Taylorville IL. Myself,my daughter, my neighbor,her stepson and my grandson. Our ages range from 8 to 49. Our husbands were in the truck just ahead of us. I first noticed what I thought was a large bright star in the lower sky right in front of us. It didn't move.the sun had just gone down behind the tree line, but it wasn't dark yet. I thought it was a star, but I started seeing more. Up to 7 at one time. I then mentioned it to the others, and we called our husbands on the cell phone. They had been watching to. They were very bright silver and moved after a few minutes and then appeared to have a tail. We stopped and took a picture, not developed yet. There was alot of traffic on this same road so I know others seen them. I found no news reports so we were very courious to hear any information on this. After they were gone we seen a dark colored helocopter flying in the area. Its hard to judge the distance but we guessed them to be over the Springfield,IL area. These were not airplanes because they sat in one place to long and then changed formation and stayed there.
