A Regional Gathering is actually the annual or biannual gathering of a local group. A true RG of all the local groups that fall within a designated American Mensa region does not exist, and not all local groups hold an RG. Confusing, eh?
Every year or two, 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.
