WHITECLAY, Neb. - Activists plan a blockade on the Pine Ridge Indian Reservation north of Whiteclay, Neb., home to several outlets that sell beer to residents of the dry reservation.

Organizers say the blockade Wednesday will be on the South Dakota side of the South Dakota-Nebraska border. Activists will make contact with drivers entering the reservation from Whiteclay for a couple of hours.

Organizers say they have the backing of tribal police, who will conduct vehicle checks, and that other law enforcement officers will monitor things on the Nebraska side of the line.

It's the third year of the blockade. It's being set up by members of the Cante Tenza Strong Heart Civil Rights Movement and the Oglala Sioux Tribe Department of Public Safety.
