We were coming home from a photo shoot. i happened to look up and jokingly said, "look, it's a ufo". then, we got looking at it, and noticed the odd shape and lights, and the fact that it seemed to be diving towards the ground. it was disc-shaped, and very large, with a lot of blinking lights. it hovered, flew straight ahead, and descended. we chased it for about five miles before we lost sight of it...Not sure where it went after that. we tried to get pics, but i couldn't get them from the car and we didn't dare stop or we would have lost it sooner than we did. we were all kind of freaking out, because we all saw the same thing, and it was no plane, helicopter, or drone, at least as far as we could tell.
