The World's Longest Yard Sale gave bargain hunters deals and steals on knickknacks and surprise treasures between Thursday and Sunday, with 690 miles of bargains that stretched down U.S. Route 127 from Addison, Mich., to Gadsden, Ala.

The giant outdoor event is organized by the Fentress County Chamber of Commerce in Tennessee. This year marks its 25th anniversary. It serves not only to clear out formerly useful wares, but also to show off the character of the 127 corridor via cultural events, food, and activities.

"The original intent of the sale was to prove the back roads have something to offer, and that the Interstate system was not the only mode for travel," the chamber said in a statement.

The yard sale has grown since its 1987 debut, when it began as a small gimmick for Jamestown, Tenn.

"A few dislike the snarled traffic associated with the sale, but all must admit, the sale is good for the economy along the corridor route," the chamber stated. "Locals sell their crafts, accommodations are filled, restaurants are crowded, and those renting vendor spaces also add to the local economy."

The boon for locals is clear, according to Leann Smith, director of tourism and membership at the Fentress County Chamber of Commerce.

"We see a clear surge in hotel and motel tax revenue," Smith told ABC News. "More people are eating at restaurants and stopping and buying gas and other necessities needed during travel. It's clearly a big difference for our small town."
