 In 2012, under pressure from the public and activist groups, the federal government agreed to reopen the park with an outer perimeter fence blocking access to the public except when permitted by the U.S. Border Patrol, which controls access to the park.The fence dividing the two countries is now a thick, dense steel mesh that is difficult to see through and only allows the touching of fingertips.Due to the work of the humanitarian organization Border Angels and its founder Enrique Morones, the U.S. government now allows a door in the fence at Friendship Park to be opened briefly on Children's Day, a holiday celebrated in April in Mexico.
