Tolls are a pain. I have an E-pass, and the PlusPass app, which handles a lot of states we travel in. Just getting back from a Grand Canyon visit, we ended up driving through Kansas, which, of course, has there own system!
When this happens are you going on line to try to pay them or just wait for them to track you down? Kansas seems to read the back license plate, which, in our case, is obscured by our bike rack anyway.
PS: Ended up with a great spot in Trailer Village at the Grand Canyon. Just by luck we had a lot of shade.
