Before attending Salt Lake's Mardi Gras Gala, we want to help you know which mystic society best suits your personality. Take this quiz to find out which one you should join for the evening! For a bit of history on what mystic societies are and their role in Mardi Gras, read on. A mystic society is a Carnival social organization (known as a krewe in New Orleans), that presents parades and/or balls for the enjoyment of its members, guests, and the public. The term came to be used in this context in Mobile, Alabama. Mystic society membership is secret. Mobile's mystic societies build colorful Carnival floats and create costumes around each year's themes. During the Carnival season, the mystic societies parade in costume on their floats throughout downtown Mobile. Masked society members toss small gifts, known as throws, to the parade spectators. Mystic societies in Mobile also give formal masquerade balls, known as bal masqués, which are almost always invitation only and are oriented to adults. Attendance at a ball requires a strict dresscode be followed that usually involves full-length evening gowns and white tie with tails for invited guests, and masked costumes for society members. The bal masqués feature dramatic entertainment, music, dancing, food, and drinks.
