You’ve probably heard of the Navajo code-talkers that helped our nation in WWII, but are you aware that American Indians were invited by the 1775 Continental Congress to join the fight against the British? This fabulous exhibit chronicles American Indians’ roles in all U.S. wars from Ely Parker who attained the rank of brigadier general in the Civil War to Bloody Knife, a Crow scout who died with Custer at Little Bighorn, to women who served as Marine reservists in WWII. Don’t miss this one! Included with park admission, $5 adult, $2 youth 7-13, children free.
