Bob gained a stepson, Dr. Michael "Mick" (Stacy) Pattinson. Bob and Alice enjoyed fourteen years of happiness together.

Bob was one of the first members of the Spearfish Jaycees, which he really enjoyed. He started farming and construction at the age of 18 and built hundreds of projects, which was an awesome accomplishment. One of his favorite projects was building Cheyenne Crossing. Bob was on the Board of Directors and a member of the High Plains Western Heritage Center. Being a member of the Northern Hills Barbershop Quartet was always a joy for Bob to sing and be with his musical friends.
