Kansas

Kansas is a U.S. state located in the Midwestern United States. It is named after the Kansas River which flows through it, which in turn was named after the Kansa Native American tribe, which inhabited the area. The tribe's name is often said to mean "people of the wind" or "people of the south wind," although this was probably not the term's original meaning. Residents of Kansas are called "Kansans." Piper McLean, Percy Jackson, and Jason Grace visit Kansas while going to Topeka, Kansas at milemarker 32.
