Where did the book sit-in take place?

The book "Sit-In: How Four Friends Stood Up by Sitting Down" by Andrea Davis Pinkney recounts the true story of a sit-in at a Woolworth's lunch counter in Greensboro, North Carolina. This historic event took place on February 1, 1960, when four African American college students peacefully protested racial segregation by sitting at the counter and requesting service. Their actions sparked a larger Civil Rights Movement across the United States.
