Many ways to say good night.

Fireworks at a pier on the Fourth of July 
spell it with red wheels and yellow spokes. 
They fizz in the air, touch the water and quit. 
Rockets make a trajectory of gold-and-blue 
and then go out.

Railroad trains at night spell with a smokestack mushrooming a white pillar.

Steamboats turn a curve in the Mississippi crying a baritone that crosses lowland cottonfields to razorback hill.

It is easy to spell good night.
