The Mardi Gras Indians are comprised, in large part, of the African-American communities of New Orleans's inner city. They have paraded for well over a century, yet their parade is perhaps the least recognized Mardi Gras tradition.
"Mardi Gras Indians--the parade most white people don't see. The ceremonial procession is loose, the parade is not scheduled for a particular time or route...that is up to the Big Chief." - Larry Bannock
