It's a short run but close to my house. Rt 27 from meadville to Titusville is pretty good. I often run that to 666 and its ok. It takes u into allegheny as Tonik mentioned. There are some other roads by Bradford that I have run as well. I believe @Danimal has run a few routes into PA. He may be able to help. I would agree with Tonik that nothing I have run in PA is as good as WV or even SE Ohio for that matter.
