Geography: Pennsylvania is bordered by New York and Lake Erie to the north. In the south, Pennsylvania shares borders with West Virginia, Maryland, Delaware, and New Jersey. To the east, New York and New Jersey line up on the Pennsylvania border. Pennsylvania meets Ohio and an arm of West Virginia on the west.
Fun Stuff: Named after William Penn, Pennsylvania is also called the Keystone State. During colonial times, Pennsylvania was the middle colony of the original thirteen colonies – it held the colonies together like the "keystone" in a window or arch. Seven important documents were written in this great state, including the Constitution, the Declaration of Independence and Lincoln's Gettysburg Address.
