have the I-Pass (or EZ Pass or whatever) sticker, which automatically deducts the toll.
El Chico and I always triple check Google Maps has "avoid toll roads" whenever we drive through Chicago because IL doesn't send out notices until after they're late, and it's a pain checking daily until your license plate is in the system...which sometimes doesn't happen until after it's late.
Total ripoff.
The PA turnpike is one of my least favourite roads I have ever driven on anywhere. I hated it as a kid. I haven't been on it since 2009 thankfully...
