When the Egyptians built the pyramids (金字塔), they included mazes (迷宫) to catch thieves. Even if thieves managed to 31 a pyramid, they would probably 32 find their way out. In 1986 the Fulks family of Fredericksburg, Virginia, decided to create a maze in their 33 on the Belvedere Plantation. Donnie Fulks and his four sons cut some 34 here and there through the tall corn. Soon this "Maize Maze" was so 35 that the Fulkses found themselves 36 a new maze each year as a new crop filled the field.

　　Some people return each year. To make it 37 for them, each corny maze is somewhat different from the 38 ones. In 1998 the Fulks family 39 the world-famous maze designer Adrian Fisher to create a huge maze 40 15 acres, or 650,000 square feet. Each new pattern was first 41 on a computer, and the one used in 2001 had to be 42 eighteen times before it was just right. After it was finished, Donnie Fulks and his sons took a detailed 43 of the pattern divided into squares, and then started the cutting job.

　　People from all over the country come out to the Belvedere Plantation to try to find their way through the Fulks family's maze. It is 44 while the corn is tall, from mid-July through early November. Visitors are given flags to 45 their progress and to wave for help if they are 46 . It always makes people 47 when they find their way to the end. Built into the 2001 maze were several 48 . Sixty speakers provided music throughout the journey. Just to be 49 , the 2001 maize maze started 50 the cornfield, making it the world's only inside-out maze!
