As a teacher, I love the idea that you're tracking a travel bug as a class project! I picked up this TB at City View in Franklin, PA. Franklin is a small town in northwestern PA, and is the County Seat of Venango County.
This location had long accommodated Indian settlements when, in the 1740’s, Scottish fur trader John Fraser began a trading post. A French expedition in 1749 laid claim to the site and, in 1753, the French expelled British traders and made plans to construct a fort around Fraser’s abandoned trading post. Later that year, a young George Washington, from Virginia, was dispatched to the region to warn the French that they were trespassing on land claimed by England. In the years following, Franklin continued a slow but steady growth, until the entire region became a center for worldwide oil production following Colonel Edwin Drake’s 1859 discovery of oil in nearby Titusville.
