Marya Callais, a citizen of Illinois, was walking along a busy street in Peoria when a large crate flew off a passing truck and hit her, causing numerous injuries. She experienced a great deal of pain and suffering, incurred significant medical expenses, and could not work for six months. She wants to sue the trucking firm for $300,000 in damages. The firm's headquarters are in Georgia, although the company does business in Illinois. Explain what court might Callais bring suit—an Illinois state court or a federal court?
