Travel Information about USA and Pennsylvania

(GMT)22 DEC 2016 THOGOO:  A short Pittsburgh introduction.
Located at the confluence of the Allegheny and Monongahela Rivers at the head of the Ohio River, Pittsburgh was referred to as the "Gateway to the West" from its early days as a frontier village. Easily navigable waterways with an abundance of natural resources, (coal, timber, natural gas, iron and limestone) helped Pittsburgh become the industrial center for a growing nation.
Most people recognize one thing about Pittsburgh's history, that it was known as an industrial hub for coal mining and steel production.
Pittsburgh has played an important part in U.S. history from the early days of the French and Indian War (1758), to the Revolutionary War (1776), to the infamous Whiskey Rebellion (1791) and the American Civil War (1860s) with its secretive Underground Railroad stops.
