Around 10:45 aug.25th, traveling southbound just past route 9 on 115, i noticed a bright light. It looked like the light on top of a phone tower. Before i could say whats that light, it passed by us at a super rate of speed. Windows down radio down and we didnt hear a thing. And we were deffinately close enough that we shouldve heard s omething. It was super bright. After it passed i turned to look but saw nothing. Very scary to me because i cant explain what we saw. We then rolled the windows up and sped up!
