HELEN — Few pastimes are more popular in North Georgia than tubing down the Chattahoochee River. So the city of Helen, as part of its centennial celebration, brought back a tradition of the past Saturday but with a new name: The Helen Centennial Tubing Parade. Popular businesses, clubs and government officials took part in the event, including the Helen Welcome Center, Helen Waterpark, Innsbruck Resort and Golf Club and more.
