During COVID-19, New Orleanians turned their houses into floats

After the 2021 Mardi Gras parades were canceled, New Orleans resident Joy Boudreaux joked on social media that residents should turn their homes into floats. They followed suit and interested (socially distanced) revellers followed maps of participating homes.

The first recorded American Mardi Gras was in Alabama

French explorers observed celebrations in what would become the United States in the late 1600s, but the first recognized modern American Mardi Gras took place in Mobile, Alabama, on New Year's Eve, running from 1830 into 1831. By 1840, the town had incorporated costumes, masks, and themes into its parade. After the Civil War, Mobile's Mardi Gras was moved to the more traditional date of Fat Tuesday. By 1850, a group from Mobile migrated to New Orleans, bringing the city's traditions with it.

Beads are social currency during Mardi Gras

Historians believe krewes started tossing small items, colloquially called "throws," to onlookers sometime in the 1870s or 1880s. Eventually, shiny beads became the norm and were usually given to those offering something in return. (At times, that meant free booze or the flashing of breasts.) The early strings of beads were glass, though by the 1960s most were plastic.
