This is a Mardis Gras arch that stays up year-round by the Tremont Hotel. Maris Gras is celebrated annually in February. Parades, bead-tossing, breast-baring, mass public intoxication, unbearably huge crowds and so forth occur. The local government authorities lose money every year on the event. A lot of the locals stay away it's gotten to be so big and messy. Still, they will do it again next year.
