This event was quite a few years ago, my family was returning to Illinois after a vacation in Texas. As driving north south of a Village called Alligator, Mississippi.What I recall a 2 lane highway in daylight to my left two objects, flat color disk shaped, black with a clear center. Not your typical saucer expectation. My wife was alarmed and urged me to slow down and let them pass. Soon a veered to the left and went out of sight. Did not appear to be much or 20 foot in dia. and fairly flat.
