Two things that aren't easy to clean up: oily pelicans and the Krewe of Oak. The irreverent group sets out on its costumed Riverbend pub-crawl/parade with the theme "Pardon Our Royal Spill in Your Wetlands." Brass bands and mini-floats accompany the procession through the university neighborhoods. Marching in the parade is free; costumes are highly encouraged.
