Best Midwest state to visit for a 4-day trip?

My girlfriend and I are planning a four-day trip during spring break this April. We’re looking for recommendations on which Midwest state(s) to visit. What are the must-see places or activities? We’d love suggestions, especially for states we haven’t explored before!
