Unless you get stuck behind a semi. My plan was to drive from the Delaware Water Gap to Erie. Six hours to go a few hundred miles I drove into New York and made good time through great scenery. Hwys 322 and 422 are nice drives. Hit the ringing rocks park in the eastern part of the state. The Grand Canyon of Pennsylvania in north central PA is nice. Once you get through Corry on 6 westbound it gets mostly straight and flat. If you plan on hitting all 67 counties I recommend at least a week. Ohio Pyle park is very nice. Avoid I 80 its all semis the exhaust fumes are almost unbearable. Back roads through the center and east part of the states are scenic.
