Another protest over alcohol sales in the Nebraska town of Whiteclay is planned for New Year’s Eve.

Two Native American groups said Sunday that they will try to prevent alcohol sold in Nebraska from reaching the Pine Ridge reservation where alcohol is banned.

The Oglala Lakota Women and Deep Green Resistance groups say they will set up a blockade on the reservation’s southern border starting at 9 p.m. Monday.

Alcohol sales in the town of Whiteclay have long been a concern for the Oglala Sioux Tribe because alcoholism and poverty are rampant on the reservation. The town of roughly a dozen people sold the equivalent of 4.3 million 12-ounce cans of beer last year.
