Steel mills played a big part in the creation of Pittsburgh, but gone are the days when you'll see any of those belching smokestacks marring the Steel City skyline. Modern glass office towers, contemporary public artworks, and theaters are more the norm these days. And Pittsburgh lies surrounded by natural beauty. The city's hilly landscape is sliced by the Ohio, Allegheny, and Monongahela rivers and bordered by the lovely Laurel Highlands, begging visitors to hit the trail, rent a canoe, or just set out on a pleasant evening stroll. Add to all of this some of the nation's friendliest residents, and you've got the makings of the perfect vacation getaway.
