Speaking of Hilyard... When I was a little kid about 7-8 years old, my parents were living in Minnesota while my dad finished up college at the University of Minnesota. After he graduated they planned to move back to Florida. But over the winter they got a chance to rent a very nice house on Gull Lake in Brainard. Some rich guy wanted to keep his pipes from freezing so he rented the house out to my parents for a low enough price they could afford. The rich guy who owned the house was Mr. Hillyard, of the Hillyard chemical company. This would've been about 1968. I've often joked there must've been something in the wallboards or something - because look what industry I landed in.
