Yeah the roads are definitely the biggest giveaway, I noticed that between Ohio and Indiana, minor rural roads go from standard 55mph two-lane roads with a double-yellow line to narrower 45mph alley-type roads that are still wide enough for 2 cars to pass, but barely. And of course everything else is still farmland so not much different. I wouldn’t be surprised if even the stores didn’t change - a Walmart is a Walmart regardless of what state it’s in.
