That's an excellent question and welcome to Free Republic.
Someone will come along who knows the answer to your question.
I was pondering this and cannot find anything on an internet search. I have never been to Mardi Gras, but from what I heard it is a big celebration of freakdom masked as a religious ceremony. I am sure some freepers can enlighten me
Mardi Gras has no corporate sponsors and is paid for by the city of New Orleans. There is a city ordinance that prohibits the use of the same float more than twice during the parade season. Mardi Gras parades have a standard order; although, not all parades follow that order. The standard order is: the parade lead by the captain (either on a float, on a horse, or in a convertible). The captain is followed by the officers, kings, queens, other royalty. Last, comes the title float and the float carriers. City officials toast the krewe royalty in front of Gallier Hall.
Mardi Gras also is celebrated in Rio de Janeiro; Cologne, Germany; and Venice, Italy.
