Georgia Pacific and Fort Howard Company welcomed retirees back to the plant Tuesday.
The "Alumni Tour" offers employees of old a chance to view changes at the plant since they've retired.
Over the next nine months, the company will hold such visits. Plant leaders say the tour is meant to show how the company has evolved and, continues to evolve, as a critical employer in Green Bay.
Plant leaders say they spent 70 million dollars on plant improvements last year alone, and say similar investments are planned moving forward.
