Got word that Colin Yennie passed today from recent health complications. Here's a pic from one of the earlier Northwestern Insulator Club shows at the old VFW across the road from the airport (and not far from the site of the 2000 National). Colin Yennie (seated) and Gary Senum are in the foreground, and I can also see Dave French, the late Earl Paulson, Joel Anderson, Mike Harders, Gary Kline, and Joan Crandall.
