South Dakota does not recognize Columbus Day as a holiday, instead we celebrate Native American Day, remembering the people who were here first.
When we first moved here, I thought that was really odd, but now I think they have a good point. To the Native American, Columbus may not be so great. He brought disease, slavery, bloodshed and ultimately an end of a way of life.
We celebrate great men in America throughout the year - President Washington, President Lincoln, Martin Luther King Jr... I think it is great that in South Dakota we also honor Crazy Horse and Sitting Bull.
You can sign a petition to make Native American Day a National holiday, if you want to.
You can also read more about Native Americans
here. I especially enjoyed reading the Trickster Tales.
