Camp Worth was built on the banks of the Trinity River. The outpost was named after Mexican War hero Gen. William Worth. Cattle industry was king for a generation of people working the Fort Worth leg of the historic Chisholm Trail. Cowboys played in Hell's Half Acre, where downtown's Sundance Square stands today, before driving their cattle on to Kansas. Fort Worth brands itself as the "City of Cowboys and Culture," featuring world-class museums, art galleries, live theater, concerts, opera and ballet along with a year-round rodeo and the world's only twice-daily cattle drive. The Stockyards National Historic District, Cultural District, Downtown, Sundance Square, Near Southside, West Seventh, Camp Bowie and the University area are all a short distance from each other. Events include the Southwestern Exposition and Livestock Show and Rodeo in winter, Main Street Fort Worth Arts Festival in April, Mayfest and Frontier Fort Days in May, Red Steagall Cowboy Gathering and Western Swing Festival in October and the Lone Star Film Festival in November.
