Located in southern Texas, off of the Gulf Coast, Houston is a major petrochemical and oil-refining center and is home to one of United State's largest sea ports. Houston is best known, however, for N.A.S.A. and the Johnson Space Center, which boasts simulated space voyages and mission control panels, teaching people of all ages about space travel. It also houses the Astronaut Gallery, the Mission Status Exhibit, the Starship Gallery and the N.A.S.A. Tram Tour. Bayou Place in downtown Houston features an abundance of international dining and entertainment options. A ride on Houston's Metro Light Rail will take you by the world-renowned Texas Medical Center, the Museum District and Reliant Park. Visitors can also step back in time at Sam Houston Park, where the Heritage Society operates a museum and some historic buildings. Sports fans have a number of professional games to see while visiting Houston, including a baseball game at Minute Maid Park or a football game at Reliant Stadium.
