Wall Drug and Corn Palace are on the list!
On our previous trip, we encountered one toll, near Chicago (we had to go that way to get to Fort Wayne, IN, to visit friends). It was about $.50! It was so novel to pay a toll that we took pictures at the toll booth--and got yelled at by the toll taker, who insisted we delete the pictures.
So....are the tolls in the $5-10 range total or are we talking more like $50? Also, Chicago got on the list because the DH saw how close it was to our route on the map and said he'd never been there and would like to see it. Should I try to talk him out of that?
