Louisville, Kentucky, is best-known as the home of the legendary Kentucky Derby horse race, held on the first Saturday of May each year. The Kentucky Derby Festival runs for two weeks preceding the race and features several major events, including Thunder Over Louisville, touted as the largest fireworks display in the United States. Another popular event is the Humana Festival of New American Plays in late February, a six-week-long festival that showcases new theatrical works. Each of the performing arts—opera, ballet, music and theater—are represented in Louisville, with performances at the Kentucky Center for the Arts, Walden Theatre and Louisville Palace among other venues. Arts enthusiasts should be sure to visit the Speed Art Museum, the oldest art museum in the state. Boasting over 120 city parks, Louisville has no shortage of green space and recreational facilities. Sports fans enjoy the ardor of Louisville's celebrated college teams, namely the University of Louisville Cardinals.
