Thanks for sharing your visit with us.
Wish there was a way you could tell him about IHCC's Harvester Heritage Preservation Program (here:
http://www.harvesterheritage.org/). It is chronicling the stories of former IH employees and recording them for future generations. The program just started about a year ago.
I'd imagine he has some IH-related stories he could share.
I really liked that round glass, wall-mounted IH sign one of your pictures from the lobby. Nice collection.
