听力原文： It seems like almost everyone buys or sells goods at yard sales in the United States. People place used personal or household goods for sale outside their homes (30) .
The LT. S. one Twenty-Seven Corridor Sale is known as the World's Longest Yardsale. It began in 1987. The event's headquarters is in Jamestown, Tennessee. A former local official, Mike Walker, came up with the idea (31) . He thought it would bring people to the area and show them that small country roads have a lot to offer. Others agreed. They wanted people to consider traveling on these roads instead of the popular interstate system.
Every year, the four-day sale begins on the first Thursday in August. So August 7th of this year marks the opening of the twenty-first World's Longest Yardsale. The event now crosses five states--Ohio, Kentucky, Tennessee, Georgia, and Alabama.
Tens of thousands of sellers take part. Some people who live along or near Route one Twenty-seven simply place their goods for sale in front of their house. Others use nearby public spaces, like parks. People sell everything and anything at the sale: furniture, clothing, toys, books and music. You can also find sporting goods, farm equipment, tools and art. And, lots of other things (32) . Tens of thousands of people from across the country drive along the road in search of interesting things to buy. Route one Twenty-Seven becomes crowded with vehicles.
