Steel and coal may have built this city, and you'll see the names "Mellon" and "Carnegie" on an awful lot of things, but Pittsburgh has come a long way from its gritty, industrial past. The Waterfront Complex, a collection of shops, restaurants, a cinema and even a water park, was recently built on the site of the former Bethlehem Steel Works, and two new professional sports stadiums have opened downtown in just the past two years. However, history buffs will delight in a visit to sites like the Point State Park (home of the Fort Pitt Museum) and the Duquesne Incline, where you can ride an antique cable car and browse displays about this unique form of transport. If you don't mind the extra drive, a trip to Frank Lloyd Wright's Fallingwater makes a rewarding detour.  More info
