Dallas symbolizes much of the popular image of Texas. A major center for oil and gas, this city goes about its business with refreshing character and gusto. For fans of modern architecture, the business core has several styles of contemporary buildings. At Fair Park, visitors are presented with a cultural and entertainment district, with attractions that include the Dallas Museum of Natural History, Dallas Aquarium at Fair Park, Science Place and Cotton Bowl Stadium, which hosts concerts and both national and international sporting events. The performing arts-dance, music and theater-are well represented in Dallas, with a host of venues offering performances that range from traditional to contemporary styles. Dallas' Majestic Theatre has been a mainstay for live entertainment and arts performances since 1921. Dallas is also home to the John F. Kennedy Memorial Plaza, a good place to meditate and get away from the fast pace of downtown.
