Saw 2 glowing amber-yellow orbs silently flying in from the ocean just south of Fort Bragg. They flew inland a mile or so and upwards into a wierd, black cloud. Then 2 more appeared and followed the same path into the cloud. Soon lines of 4 and 8 came in like freeway lines at 3 different levels, all into the bottom of the growing cloud. Sirens in nearby Ft Bragg went off. Heard neighbor yell on the phone "Ive never seen anything like this!" Lost count at aroung 150 total Last few came , 2 joined into one and flew into the cloud and that was it
