A larger UFU that was around 5 cylinders together and around 200 feet wide and long, and smaller UFO that was just one cylinder.I took around 20 pictures however only 2 pictures showed the ships. I/we only saw the large ship, it was only after looking at the pictures that I/we noticed the smaller cylinder shaped ship. I was with my boyfriend and on the phone with my Mother asking her if we could follow the UFO and she said we could if we stayed on the phone with her. We both saw lights about 200 feet above the ground near some farmland to the West of Hwy 91 near Fairview, Idaho. These lights rose up making a diamond shape and went to the mountains to the East of Hwy 91 around 20 miles away. We followed the ship south on Hwy 91 from Preston, Idaho, to Lewiston, Utah. It seemed 200 feet long and wide, and at first it looked like just lights that were diamond shaped with white lights radiating and pulsating. However in the picture the lights are green and it’s not a diamond shape, it is several cylinder shaped vessels put together as one ship. It disappeared right before our eyes. We only saw the smaller single cylinder shaped ship after, when we looked at the picture that shows it.
