This makes the 4th time this week i've witness something flying in the air that i cannot explain. this time saw what i thought were black and orange halloween balloons flying over some power lines in my back yard. they seemed to be traveling on a path like helium balloons would, almost like a straight line up in the air, all the while spinning in a tumbling and rotating triangle. i shot some video. if this is someone just trying to pull a halloween prank, it's a darn good one.
