Hall County superheroes will gather at Road Atlanta today for the county’s annual Relay for Life event, sponsored by the American Cancer Society. The event, with the theme “Superheroes Fighting Cancer,” will feature more than 100 teams and thousands of area cancer survivors during its six-hour reign, beginning at 6 p.m. “The teams will have games, some of them will have activities,” said event leader Rose Riddle. “Some sell food, and it’s some of the best food in the world out there.”
