On behalf of Mom, Keith and I, we just want to share our condolences. Katherine's friendship was important to Mom and I know she will be missed by all. The DQ mention in her obituary made me smile as i remember bringing Katherine up to visit Mom from Iowa City and we passed a DQ in a small town in WI and we had to stop. Mom still enjoys sharing stories that go all the way back to the Waterloo days. Our thoughts and prayers are with your family.
