With the pandemic still wreaking havoc in the U.S., the party preceding the start of Lent moves to a mostly virtual setting, ensuring that the spirit of the special occasion lives on. In New Orleans — where millions gather in a normal year to celebrate — the popular “Krewe of Bacchus” social club was one of many organizations forced to cancel its extravagant parade held before Fat Tuesday (Feb. 16). Instead, they unveiled an app called “Throw Me Something Bacchus,” in which fans can create an avatar, check out floats and marching bands, enter to ‘catch’ digital prizes and attend a virtual edition of the Bacchus Sunday Parade set to stream at 2 p.m. on Feb. 14.
