The field of horses charges down the stretch in the seventh race at Churchill Downs in Louisville, Ky., on June 19, 2009. The day marked the first night racing at the storied track in its 135-year history. Track superintendent Butch Lehr is retiring after Saturday's race. He's been maintaining the track since 1982.

Lehr rolls in a section of a mosquito trap which is set up near the turf course at the track Aug. 13, 2002, in Louisville, Ky.
The surface on which Kentucky Derby horses will race Saturday is a special piece of real estate, built for high performance and safety. The track is generically described as dirt, but is actually a careful mixture of river sand, silt and clay.
In this photograph of a courtroom sketch, Khalid Sheikh Mohammed, charged with orchestrating the Sept. 11 attacks, attends a court hearing at Guantanamo in 2008. He's expected to appear in a military court Saturday.
Khalid Sheikh Mohammed and four other men charged in the Sept. 11 attacks were supposed to be tried six years ago in a military tribunal created by the Bush administration.
But that system — which allowed hearsay evidence, among other things — faced questions about its fundamental fairness. When President Obama came into office, he put all the proceedings at Guantanamo on hold and asked that the commission system be revamped.
Since then, there has been an effort to make sure the trials at Guantanamo are credible, with both Congress and the Supreme Court weighing in.

Hours after Facebook put out a call Tuesday for its users to register as organ donors, 6,000 people had already signed up. That's more than 15 times the number of people who normally register each day, according to Donate Life America, which is collaborating with Facebook.
Dominique Strauss-Kahn, the former chief at the International Monetary Fund, is facing more allegations of sexual misconduct.
Strauss-Kahn was considered a top contender for the French presidency until he was accused of rape by a New York City hotel maid. That case against him was dropped, but it cost him his IMF job and then French investigators implicated Strauss-Kahn in a prostitution probe.
Two brothers have been charged in connection with one of the nation's largest drug heists, along with 20 other people in an organized crime ring that stretched from Florida to New Jersey and Connecticut.
It's the culmination of a three-year FBI investigation in which undercover agents managed to prevent any of the stolen drugs from entering the marketplace, the Associated Press reported yesterday.
Barack Obama and Mitt Romney just may be the same person. Think about it. Have you ever seen the two of them in the same limo?
All right. Of course, the pair of politicians who will in all likelihood be the major party nominees for the 2012 presidential election have their differences. Republican Romney, for instance, has been a governor and chairman of the Olympics; Democrat Obama has not. Obama, on the other hand, has been a senator and a president. Romney has not.
Free Syrian Army members from the al-Faruq Brigade arrive to attend the funeral of one of their comrades at the Khaled Ibn al-Walid mosque in the al-Khalidiyah neighbourhood of the central Syrian city of Homs on Thursday.
Here at The Salt, we've taken note of the all-too-common habit of letting food rot in the fridge. Food waste can cost hundreds of dollars a year, and once it arrives at a landfill to decompose, it turns into a greenhouse gas that contributes to global warming. And that makes us feel guilty.
Now some home appliance companies are banking on the hope that some consumers will turn over their food waste worries to a computer inside their fridge.
The movie Rhapsody in Blue, a biography of George Gershwin, was released only eight years after his death from a brain tumor at the age of 38. It's a good subject: Gershwin wrote some of the best popular songs ever produced in this country, but he also had ambitions to be a serious classical composer and wrote symphonic music, concertos and an opera — all of which are still performed.
Saying that the rules would "make sure that fracturing operations conducted on public and Indian lands follow common-sense industry best practices," Interior Secretary Ken Salazar this morning issued proposed regulations that would:

-- Ensure that "wells used in fracturing operations [on public lands] meet appropriate construction standards."
-- Require operators to "put in place appropriate plans for managing flowback waters from fracturing operations."
The bake sale, a staple of school fundraising for generations, is getting squeezed. The epidemic of childhood obesity is leading some districts to restrict the kinds of foods sold or to ban the sales altogether, Bloomberg Businessweek's Stephanie Armour explained on Friday's Morning Edition.
