“House of Heroes” pays tribute to front-line health care workers. The iconic song “The House of the Rising Sun” comes to mind when you learn the theme of the Audubon Riverside subkrewe of the Krewe of House Floats. “There Is a House in New Orleans” is the theme, and many houses are already wowing passers-by (and drivers-by). Audubon Riverside has 170 official houses that will appear on the map that will roll out on the KoHF website on Feb. 1. The subkrewe’s captain, Courtney Guidry, saw some chatter about “house floats” around Thanksgiving and posted a question on whether her neighborhood was going to be included. With that, Admiral Megan Boudreaux asked if she wanted to serve as the area captain.
