How did so many people get Orlando without having to get Orland Park on accident first?

Maybe you used to have to type "park" as well and the quiz was updated?

Removed Orland Park since it was the least populous answer and also very unessential.

"Has an apostrophe in it's name"

But there shouldn't be an apostrophe in "it's".

Great to see O'Fallon get a mention on here! There's another one in bordering Illinois founded by the same person. Both cities are part of the St. Louis metropolitan area.

Enjoyed the quiz, thanks. Although you missed your chance to be extra clever and say "Littorally, along the sea"!
