Whiteclay, Nebraska is a tiny unincorporated town that sits on the border with South Dakota. Until its closure by state officials, its four liquor stores sold more than 4 million cans of beer a year, almost entirely to members of the Lakota Sioux tribe on the Pine Ridge Indian reservation, where the sale of alcohol is banned. The Guardian spent time on the reservation to understand the impact of alcohol on its residentsnd the activists and Lakota tribe members determined to keep the town closed.
