KINGSPORT — Pratt’s Big John Indian is currently under repair and will soon have a new, more durable head. Two weeks ago Big John — the iconic sculpture that stands in front of Pratt’s restaurant — suffered a near catastrophic injury. His neck broke and his head slumped down to his chest. That night and the next day, people kept calling the restaurant to let them know what happened or to ask employees what had happened to their beloved sculpture.
