Millions of Americans return from long-distance trips by air, but their luggage doesn't always come home with them. Airline identification tags  can come loose, and the bags go who-knows-where. And passengers leave all kinds of things on planes. The airlines collect the items and, for 90 days, attempt to find their owners. They don't keep them, since they're not in the warehouse business. And by law, they cannot sell the bags, because the airlines might be tempted to deliberately misplace luggage. So once insurance companies have paid for lost bags and their contents, and they no longer belong to passengers, a unique store in the little town of Scottsboro, Alabama, buys them. The "Unclaimed Baggage Center," is so popular that the building, which is set up like a department store, is the number-one tourist attraction in all of Alabama. More than one million visitors stop in each year and take one of the store's shopping carts on a hunt for treasures. Each day, clerks bring out 7,000 new items, and veteran shoppers rush to paw over them. You can find everything from precious jewels to hockey sticks, best-selling novels, leather jackets, tape recorders, surfboards, even half -used tubes of toothpaste. The store's own laundry washes or cleans all the clothes found in luggage, then sells them. The Unclaimed Baggage Center has found guns, illegal drugs and even a live rattlesnake. The store has a little museum where some of its most unusual acquisitions  have been preserved. They include highland bagpipes, a burial mask from an Egyptian pharaoh's tomb, and a medieval suit of armor. Statistics indicate that less than one-half of one percent of luggage checked on U.S. carriers is permanently lost and available to the store. What is the main purpose of the passage?
To introduce an attractive place to tourists. To remind passengers of taking care of their baggage. To advise the airlines to find the owners of the unclaimed baggage. To introduce how the unclaimed baggage in the airports is handled in America.
