Don was an amazing family man. He took his family snow skiing, water skiing, hiking, biking, camping, and "off-roading" before it was a "thing".  He loved to drive anything, anywhere, but especially his Motorhome,  in which he traveled, literally, all over the world with Yvonne.  He was an impressive do-it-yourself, hands-on, kind of guy!

Don was very much involved in the Deadwood community.  He was active in Jaycees and Toastmasters, emceeing many events. Don organized the annual Auto Dealers float for the days of 76 for many years. He was president and member of the Adams Museum Board, President and a member of the Deadwood School Board, was on the Deadwood Chamber of Commerce Board of Directors, the Twin City Community Development Board, Member Broken Boot Gold Mine Board and more!
