About Kansas City

Learn more about the host city, Kansas City.

Kansas City is a major Midwestern metropolitan area that spreads across the border of Missouri and Kansas. It is a city that tends to hide itself from tourists. Reputed to have more boulevards than Paris and more fountains than any other city in the world except for Rome, it can be a beautiful city, too. It is unique in that it is split down the middle by the state line of Kansas and Missouri.
