Gerald enjoyed deer hunting, fishing and playing cards with his buddies. He loved to have people visiting him and could banter with the best of them. If there was a deal to be had, you wanted Jerry on your side of the negotiations! He had a great mind for math and imparted to his children the importance of getting good grades, working hard and saving money.
