Since 1997 Microsoft and Bill Gates have been holding an annual very exclusive “CEO Summit.” The inaugural 1997 conference introduced his 50,000 sq ft, $150 million, Lake Washington estate that was near completion. Usually about 100 top-level people from around the world attend. Sessions and meetings are held at the Microsoft campus and Bill’s estate, aka his personal Convention Center. Most of the meetings and social events are closed to the media and public and advance notices of the times and places of these are not provided. The above is a guide to his lakefront convention center as viewed from the public waters. The estate along with more information is in my book, Lake Washington 130 Homes, on pages 118 and 119 (www.hundredhomes.net).
