    Such a full life, so many talents, so many stories. I wish he had written a book… surely a bestseller.

    We have enjoyed many Thanksgiving and Christmas dinners together as your next door neighbors. We will surely miss sitting by your pool and our pool as well, in summers past. We know that you are with the Lord now and all is well with your soul. We will help take care of your beloved Jan as long as she lives next door, until you meet with her again. Much love and comfort to all the family.

    Dear Winkler Boys – It has been some time since your father’s death but we just became aware. We send out sympathy. We still have so many fond memories of all of you and your parents – the fun times on Goff Road and Upper Drive. Love and peace – Gene and Judy Baisch
