The Dallas-Fort Worth metro area offers an interesting mix of Texas pride and cosmopolitan offerings. The cowboy life still exists in Fort Worth, while Dallasites love the trendy local bars and numerous retail shops. The Fort Worth Stockyards National Historic District was once the biggest and busiest cattle, horse, mule, hog, and sheep marketing center in the Southwest. Authentic western buildings house Old West shops and restaurants. The Cowtown Coliseum features Wild West Shows, rodeos, and concerts year-round. The Cavanaugh Flight Museum is one of the finest privately-owned collections of vintage war birds in the country, covering World War II through Vietnam. The Dealy Plaza and the Sixth Floor Museum, located in the former Texas School Depository, examines the life, death, and legacy of President John F. Kennedy with over four hundred photographs, artifacts, displays, and videos.
