So if you have the day off on Monday, why not spend it in a national park near you? You can locate one at FindYourPark.com. It’s the perfect way to celebrate the beauty, history, and heritage of our nation.

Visit the Martin Luther King Jr. Memorial in Washington, D.C., or honor those who progressed the civil rights movement at sites like Selma-to-Montgomery National Historic Trail.
