Ken enjoyed puttering in the yard and feeding the birds and rabbits.  Together, he and Jean enjoyed many adventures, whether it was trips to the Dells, going to flea markets, or various bus trips.  In his younger years, he enjoyed camping on their land in Beecher and in Wisconsin Dells.  He loved to fire up the grill and his 8-track player, as well as a good prank.

Family was at the center of his world, and he cherished the time he spent with them.   He loved hosting all of the holidays and had special traditions for each one.
