After winning/losing ?- our high school football game, myself and 3 other guys hopped into a convertible car and started driving around town and the countryside. Someone shouted look there and pointed up. There were 6 bright green globes floating around, with no sound, flying in formation. First one then two then three in the formation. They flew around in all kinds of directions, and making corners faster and closer than a jet of the day could possibly have done. During the whole show, they did not once break formation, then after about 20 minutes, they were gone, but after so many years, I do not remember how they left the scene. I had heard about flying saucers of course, and I am a true sci-fi buff, but it was really amazing and very exciting to see something like that! About 20 minutes after they left, there was a huge flash of light behind Black Butte just to the North East of town. A flash of light that disappeared immediately.
