Register to attend Michigan’s biggest Mensa event of the year: Regional Gathering or RG 2017

It is hard to believe that for the 38th year in a row we will have the opportunity to attend a quality, fun filled weekend. You can discuss a myriad of topics with fellow Mensans at the 24 Hr hospitality room that is stocked with sinful/gluten free snacks & drinks, or satisfy your craving for chocolate desserts, and attend mind expanding lectures on topics ranging from the latest findings about our nearest plant Mars to Detroit musicians who have dedicated their entire lives to creating music, or simply play board games against friendly and skilled players. Perhaps you may like to participate in team Mensa Bowl Challenge – try coming up with answers to some of the most mind twisting questions, or if you prefer, participate in mind-blowing Mensalympics.

Dr. Harry Ringermacher, a retired Senior Research Physicist from the General Electric Global Research Center, and the Chairman of the American Copper Black Creativity award, and the only Mensan to win the award twice, will be the keynote speaker at the event. On August 21, 2017 a total solar eclipse will cross the US from Oregon to South Carolina. Totality will last 2 1/2 minutes. Dr. Ringermacher will be at St. Louis to photograph the event. He will discuss in detail about the event, best places to see and capture the eclipse.

Dr. Ringermacher will make a keynote presentation aptly titled “The Great American Eclipse of 2017”

Guided by Melissa Jenkins, kids have their own activity track too. Whether they like to take apart old electronics, computer equipment, try out Karaoke, participate in a band/dance contest, know more about world Travel by Dave Cahn of Metro DC Mensa, make and interpret their own blood smear, hear cool tips and tricks about computers, participate in Minecraft Block Building, build their outer space home, participate in Lego building contest, or simply savor the taste of chocolate desserts, the weekend is packed with activities that will keep them fully occupied.
