Finding new places is great but I just avoid the Penna Turnpike because it's not worth the prices. When coming back to Pittsburgh from Ohio I've learned to get off the Ohio Turnpike at I-80E then run 11S to the Ohio River at East Liverpool. It's only half an hour on Route 30 before it merges with 22 and you are back on the freeway.

Leaving the state for Ohio I do take the turnpike because it's free from I-79 to the state line. Westbound only. I don't remember what the price is eastbound but I do remember it was more than I wanted to pay. Maybe $12 by now?
