I am taking my family from Pittsburgh to Kansas City and back this weekend. I have seen a farm or tractor museum on the side of I-70, but I don't even remember which state it was in, It had to be between Dayton and Saint Louis, Which is a pretty big area!
Google gave me this place in Greenville, IL, but that is farther west than I was thinking.
Is there something else I am thinking of? Anything else fun on the way? I want something the kids will like, and a place to run around in a long car ride.
