I am curious about a nice route to travel through PA, on a north to south route because I am heading down to Maryland for a couple of job interviews. I am coming from the Adirondack region in NY,and I want to eventually make my way to the Harrisburg area so I can continue on my way to MD. I am looking for a fun and scenic route through PA. When looking at the map, there doesn't seem to be a lot of roads that go north-south in central PA. The only one I really notice is RT. 15. Thanks!
