On this week's edition of " All Things New Orleans " we're talking all things Mardi Gras! First, we'll get a quick lesson on bead history; from precious throws to the controversial "Forever Lee Circle" beads. Then, Tegan Wendland chats with Dani Galloway, interim head of the Department of Public Works. They'll talk about city officials' plan to protect gutters from unwanted beads and trash along the parade route.
