Russ was a man of few words, but he was very proud of his kids and grandkids. They brought him unending happiness. Russ was passionate about the game of golf and also enjoyed watching sports, especially the Badgers, Packers and Bucks. He loved watching “The Godfather” and all of Clint Eastwood’s movies. Baking was another of Russ’s pursuits. He loved baking scones and Norwegian goodies: Æbleskiver and krumkake. Russ liked playing cards and getting together with family and friends. He was the Trivial Pursuit game master, with everyone wanting to be on his team. Russ was an excellent woodworker; his creations included, Adirondack chairs, a wishing well, a working windmill, and a lighthouse. Many good times were had at Karl Ray Lanes in the 80’s where he and Sue bowled in a couples’ league. Russ was a member of American Legion Trier-Puddy Post #75, the Fraternal Order of Eagles Aerie 270, and the Fond du Lac Senior Center.
