Hail, loyal subjects! In New Orleans, we are all fortunate that the krewes and their members throw parades for everyone's entertainment. Rex Duke™, Carnival's foremost parade reviewer, salutes them. Longtime followers of my annual reviews will note that, once again, I have dispensed with using crowns (and half-crowns, as if there were such things) to rate individual krewes. While I love traditions, what would Mardi Gras be without evolving tastes and styles?
