How did a state with the Appalachian mountains, major cities, a major tributary of the Mississippi, and a Great Lake make your bland list. You want to see nothing? Go to Iowa. The Great Plains are a magnificent ecosystem with immense value, but gods is it a boring one to look at. You glimpse at it and are just like “yep, it’s grass and farmland”.
As a kid we drove from Dayton to Denver and yeah that chunk of Ohio is boring, as is that chunk of Indiana and Illinois, but once you pass the Mississippi holy fuck is there just nothing until mountains show up. It’s like being on the open ocean
