The day before the Green Bay Packers kick off their 100th season as a professional football franchise, they’re going to host a giant party. The Packers announced plans for a “Celebration Weekend” yesterday (Monday). It will take place outside Lambeau Field Saturday, September 8th. Celebration Weekend officially starts at 4:30 P-M and a concert by the Steve Miller Band is set for 7:30. Parking will be free. Fans will be able to take stadium tours and eat at the Packers Hall of Fame or go to the Packers Pro Shop. The landmark season starts the next day with a game against the rival Chicago Bears.
