I live in Polk County Florida. There are an unusually large bunch of ignorant "Git-R-Dun" rednecks in Polk County.
That being said.
That was when some fool county employee lit a brush fire to clear brush away from I-4 and added smoke to fog and caused a 70 car pile-up on the highway. To illustrate the intelligence level here one fellow said, "The fog was so thick I had to slow down to 50 mph and somebody hit me in the rear."

So you get the fool with his Wal-Mart Video camera filming a jet con-trail for several minutes in the sunset colored by smoke and he yells UFO! If it was a UFO, fool, it would not be visible for several minutes.
