Sioux City East is a high school in Sioux City, IA. It is a great school, but gets a bad rep for being the “rich” school. They beat North and West at everything, and that is just how it is. Despite the teachers being confusing, the students being fake, and the building being shit...it’s definitely the better school of Sioux City
Person 1: Where do you go to school?
Person 2: Sioux City East
Person 1: Hey, at least it isn’t Sioux City North!
