Cairo, Illinois is a Real Place?📖💭

Cairo (/ˈkɛəroʊ/ KAIR-oh)

When I was watching the 1974 musical 'The Adventures of Huckleberry Finn' last week the African American slave Jim's goal was to get to the town of Cario, Illinois and there was even a musical number about Jim's hopes and dreams titled 'Cairo, Illinois' sung by the actors Jeff East and Paul Winfield.

I thought Mark Twain had just made up the name like he did for the town of St. Petersburg he wrote about in those novels. 

But, no Cario, Illinois is a real town with a bleak past it seems when you read about the town's history on the town's Wikipedia page.

Greetings from
Cairo, Illinois

I wonder what Twain would have written about the town and its history if he was still alive in 2023?

I guess even the real Cairo in Egypt has changed a lot since Twain's day?
