Description: I was driving northbound on I-205, approaching the area of Rocky Butte, Portland, Oregon near the Portland International Airport. I am looking northbound, following a semi-truck. I am in the middle lane, in heavy traffic. I was looking towards Vancouver, Washington. I was looking also towards the sky, above the back of truck, panning the sky. I see three separate auto lights approaching towards me on to my left, mid-way up in the air-space, I had to watch traffic for there were several lane changes in this area. As I continued northbound watching the lights, the light is the size of a car headlight, from this distance. It was a small object, round sphere, light in front, black, three separate objects, not in a row. I am traveling 55 MPH. These three objects were going southbound, above traffic, going 120 MPH plus, faster than auto traffic below. I am passing them going northbound. These 3 objects have white headlights, black round shapes traveling southbound at 110+ MPH with the traffic. They were staggered and not in a perfect row. They were 7 to 10 to 8 car lengths apart. Where these drones? A very small A small airplane would be a giant next to these small objects. I am near the Portland International Airport. Also I am familiar with helicopters. They would not be traveling this low, with this traffic next to low power lines. If you can send a fax number, I can draw a picture and fax you. Thank you.
