The recipe for Derby Pie has been a closely guarded secret for the past 60 years.
LOUISVILLE, Ky. (WDRB) -- The University of Louisville says the mold is gone from its dormitories, and it's ready for thousands of students to move in on Aug. 21.
That includes a record freshman class.
Last month, mold was found in Threlkeld Hall and so-called "small areas" were discovered in Unitas Tower and Miller Hall.
It came less than a year after mold forced an evacuation of Miller Hall, where the heating and air system, and all the furniture was replaced.
This time, crews tore apart more than 100 rooms in Thelkeld, and replaced all the wooden wardrobes.
The school says U of L's image is quickly changing from a commuter school to a residential campus.
And 2,000 of the 5,200 students living on campus will be freshmen.
