Suburb of Columbus, Ohio. Home of Westerville South High School, and where bagpiper grew up and went to high school. Westerville is in fact the real city featured in the Christian Slater and Wynona Ryder movie Heathers, as "Westervelt". Seat of the Prohibition movement, where Article 18 of the United States Constitution was penned. Westerville also has the higest per capita ratio of on-duty police officers in the midwest. God save us from suburbia.
