Discoveries...America, Pennsylvania
From the rolling forest-covered hills of rural Pennsylvania to the modern urban centers, Penn’s sylvan, or Penn’s woods, is the subject of the latest Discoveries…America program.  Journey back in time through the cobbled streets of Philadelphia and uncover a wealth of national treasures – the liberty bell, Independence Hall and the U.S. Constitution to name a few.  Nearby, Valley Forge puts the American Revolution into context at the new National Center for the American Revolution while Gettysburg continues to be an important historical shrine.  Visit a small artist’s studio in the woods where Wharton Esherick, an important American artist and sculptor, worked with wood and the studio he built is now a museum for his creations.  Take a ride on down scenic back roads through Covered Bridges and past Painted Barns ("advertising barns"), which tell their own stories about early American workmanship.  To the west, Pittsburgh, a city once known for its pollution, has!  changed its direction and is now vying to become one of the cleanest cities in America. Go inside their new convention center to see what makes a building ‘green’ and meet hundreds of rare and exotic birds at the National Aviary.  Farming is a way of life and agriculture is still the most important industry in the state. Modern dairy farmers tend to hundreds of acres of crops with huge harvesting equipment while their Amish neighbors perform the same tasks the old fashioned way - using only horses and mules.  From "red, white & blue" to "green", Pennsylvania in the 21st century is a remarkable contrast of cultures and lifestyles.
