I had a tour of the plant some 20+ years ago. The place is huge. When the plant was being built it had to take a long time to grade the layout before they even put in the steel work. I live near a school that converted a baseball field to a football/track field. It probably took 4 months if not more to level out the field before even getting started on putting in the football field, stands and dressing rooms.
Small world!
I think it’s now a Rivian truck plant. Yep. Just checked.
