Grand Assembly in Massachusetts

Massachusetts always holds their Grand Assembly the last full weekend in June every year.  It is a time where all the Assemblies from around MA and outside Massachusetts come together to celebrate their accomplishments, award Scholarships to our Members, and just enjoy each other in a convention setting.
