On Saturday, Warroad's hockey programs will recognize Native American survivors of the boarding school era, when the U.S. made attendance mandatory in residential boarding schools, during a doubleheader at Warroad Gardens Arena. The girls play at noon, followed by the boys at 2 p.m. Les Sandy, the grandfather of Warroad hockey players and former state champions Katierie and Kaiya Sandy, is a survivor and Ojibwe elder. He will share his experiences living at a Canadian residential school.
