NEW ORLEANS (AP) — You just can’t keep a good city down, especially when Mardi Gras is coming. All around New Orleans, thousands of houses are being decorated as floats because the coronavirus outbreak canceled the elaborate parades mobbed by crowds during the Carnival season and on Fat Tuesday. Some smaller groups announced no-parade plans before the city did. But the “house float” movement started almost as soon as a New Orleans spokesman announced in November that parades were off for the season. Megan Joy Boudreaux says it started as a joke on Twitter, but she began to like the idea and started a Facebook group called the Krewe of House Floats.
