This past August, NHL players along with the Hockey Diversity Alliance went on strike for two days during the playoffs. One of the demands of the strike was that the empty arenas around the country be used as voting centers for today's US General Election.
The Arizona Coyotes responded to the player's decision with support and stated that they would begin working with the City of Glendale to have Gila River Arena serve as a polling site. On September 4th they made it official, Gila River Arena would be a polling site for the election.
