Saw like a helicopter type thing going low over I-5 but I really couldn't tell if it was a helicopter, that is why I'm saying a helicopter type object thing. I tried to see if there were any spinning blades on top or on the tail but it was going in front of us so fast, in front of our moving car. I did see like a sliver light blinking on it that I could see very well. Just thought I would report this because I just couldn't quite tell if this was a helicopter or a helicopter type object thing.
