Opponents to the reroute of Highway 55 in south Minneapolis have been camped out in the path of the highway for more than a year. Young people from the environmental group Earth First have chained themselves to trees and bulldozers. Dozens of them have been arrested. Early on in the battle, Earth First enlisted the help of a group of Native Americans known as the Mendota Mdwakanton Dakota. The Mendota Dakota say the land the highway will pass through was sacred to their ancestors.
