As I was waiting outside for my uber I looked up to see a sting of 6 lights flying right behind each other . It got my attention so I continued to to watch as more lights added on coming from out of nowhere and getting in the back of the line .In there 3 minutes or so that I watched I counted331 lights . When my uber arrived I pointed the lights out to him .He alsofoundthem very unusual .just white round lights .There were no colored or flashing lights visible . If I had to guess from my view on the ground about an inch apart and were going from my left to the right staying at what seemed to be the same height.
