Dallas is a center for business, arts, and Texas culture on the Trinity River. The Dallas Arts District is one of the largest urban arts districts in the country, with the Dallas Museum of Art, the Nasher Sculpture Center, and performance halls close together. The Sixth Floor Museum at Dealey Plaza tells the story of President John F. Kennedy, Klyde Warren Park covers a freeway with lawns and food trucks, and the Dallas Arboretum and Botanical Garden offers seasonal displays on White Rock Lake.
