Dearest Phyllis and Family, I am so deeply sorry for the loss of your beloved Gene. He was such a kind, welcoming man with a dynamite smile. I have such wonderful memories of going to your house to be pulled around for the annual fall hayrides. Gene will be sorely missed, but live on in those who knew him. Please let me know if there is anything that I can do to help during this (or any other) time. Much love and light to you and your family, Ruth Korsten Shurtleff
