Teens rest in a state fair tent

　　Behind the scenes at the Iowa State Fair, kids tuck in for a rest during the four-day livestock event. Beyond the couch, cattle owners prepare a calf for the show ring. Cattle competitions have been part of the Iowa fair since its beginnings in 1854, when perhaps 7,000 people attended the exposition. These days the annual fair draws more than a million visitors and brings at least $60 million into the Des Moines economy.

　　在州博会帐篷中休息的青少年

　　爱荷华州博览会上为期4天的家畜竞赛期间，后台的孩子们挤进被子在长沙发上小憩。沙发后面的牛主和牛犊为出场比赛而整装待发。从1854年首届爱荷华州博览会起，便有大约7,000位观众参加了家畜竞赛，自此，这项活动便成为了爱荷华州博览会的一部份。这几天的年度博览会吸引了超过100万位观众，这给得梅因带来了至少6,000万美元的经济效益。
