Deere in Waterloo Iowa - my father was a management consultant and spent a few years working on process improvements in Waterloo Iowa for Deere. In fact, I went on a trip with him one week to watch and learn and we played basketball at your YMCA. RANDOM fact for sure but true... I would say around 1988 or 1989. His name was Tom Montague as well.
Now ow the only time I visit Iowa is to pheasant hunt or to fish for giant smallmouth bass at Okoboji.
Have be a great and safe holiday.
Tom
