While American Mensa is broken into “regions,” each encompassing multiple Local Groups, an RG is actually the gathering of a Local Group — perhaps annually or biennially . In this sense, a true “Regional Gathering” of all the local groups that fall within a designated American Mensa region does not exist. Also, please note not all Local Groups hold an RG.
Every year or two (sometimes less often), MWW hosts or co-hosts a Regional Gathering. In 2011, instead of hosting a Regional Gathering, we were pleased to co-host the Annual Gathering with Oregon Mensa.
In 2017, we hosted the Emerald City RG, Return to Oz.
