Maybe Scranton, Pa. was not on your bucket list -- ever. But this northeastern Pennsylvania city deep in a valley of the Appalachian Mountains holds significant history throughout, including the Steamtown National Historic Site, as Kathy Petrino learned among her many nationwide travels. This adventurous writer took a pause in Scranton to learn how it received the moniker of “The Electric City” and many signs pointed toward a rich history in locomotives, specifically the first electric powered streetcars debuting in Scranton. Petrino gained more of this background at Steamtown National Historic Site, a 62-acre heritage railroad yard and museum dedicated to trains. With buildings dating back to 1899 and 1902, used for the Delaware, Lackawanna and Western Railroad and others, this National Park Service travel destination is full of details on the industry and its northern importance across the last two centuries.
