Pennsylvania is known as the Keystone State, because of its central geographic position in relation to the 13 original colonies. It is the state where declaration of independence was was signed and the home of the first continental congress. Our constitution was written here. Pensylvainia means Penn's Woods named after William Penn. I believe he was granted this large tract of land from the King of England. Pennsylvania is home to "the sweetest place on earth", Hershey, PA. It's where the original Hershey Bars were manufactured and remains home to Hershey corporate headquarters. Our state tree is the hemlock, flower; mountain laurel, bird; rough grouse. In the past coal minning was a big industry, as was steel. We still produce all kinds of agricultural products including; dairy, poultry, beef, corn, apples, peaches, pears, & berries. We still have many forrests and continue to produce lumber. You know, when she cites the source of this information my name won't hold a great deal of academic credibility. Good luck to Izzy. She should cite me as a quilter and resident just remembering what I learned in elementary school.
