People love walking through a giant puzzle. In a corn maze(玉米迷宫), they can follow miles of paths and run into lots of dead ends before they finally find their way out. The corn maze has been growing for almost 30 years. 

Simple corn mazes began appearing in the 1980s. In 1993, the first big corn maze created for the public to enjoy was made in Annville Pennsylvania, by Don Frantz and Adrian Fischer. Then, in a corntield as big as two and a half football fields, Mr. Frantz created "The Amazing Maize Maze"with the help of his family and friends. When it was done, almost two miles of pathways snaked through the cornfield. Since then, thousands of corn mazes have been created around the world.

For many farmers, a corn maze means a boost(激增) of extra income. During the opening weekend, about 6, 000 visitors came to get lost in Mr. Frantz's maze. Charging only $5 per person, he earned almost $32, 000in two weeks.

Brett Herbst is also a maze designer. In 1999 he set a world record for the world's largest corn maze, an image of the solar system with nine planets in it. He now has a business called The Maize, which has designed more than 4, 000 mazes around the world. "Corn mazes help people connectwith their roots, "he says. "People are so far removed from farm life that they are drawn to something real, something organic. "

Today, a great number of people enjoy seeking fun in a corn maze. Mr. Herbst says, "When we see families on the farm having fun, we know that they are making memories that will last a lifetime. "
