Title: Pennsyltucky
Content:  Much of the term's history evolved from the Appalachian area of Pennsylvania, which includes most of the T and most of the Pittsburgh area. Since the early 1800s, Pittsburgh has been one of America's major cities with a distinct association to the Midwest. Its geographic proximity to Ohio and West Virginia creates an Ohio River Valley feel in contrast to the near coastal metropolis of Philadelphia surrounded by Delaware and New Jersey. Pittsburgh did not grow radially as most other major American cities but resembled a miles long "spider" of urbanity down river valleys such as the Monongahela, Allegheny, Chartiers and Beaver among others. For much of the 20th century the result was a major sprawling metropolis that just a mile on either side of the valley was as wild and natural as the most remote parts of the state. Even with today's suburban sprawl, very wild bluffs and hollows remain as a web of "green belts" throughout the Pittsburgh metro area. For these reasons notable people familiar with Western Pennsylvania also include Pittsburgh and its immediate area in the "Pennsyltucky" definition.
