Pittsburgh residents seem to derive a certain joy from traversing its hilly terrain, whether it's crossing the Roberto Clemente Bridge to visit the Carnegie Science Center, or heading up Mt. Washington for a glimpse of the stunning skyline. Despite its reputation as an industrial hub, Pittsburgh contains many cultural institutions. It lays claim to the world's finest museum devoted to Andy Warhol and features many other resources for fans of dance, theater, music and film. Aware of the fitness needs of its citizens, a continuous 245-mile jogging and biking trail connects the city to Washington, D.C. through the Allegheny Mountains. Such flourishes help make Pittsburgh one of the most enjoyable and livable cities in America.
