No booze at Mardi Gras?

What's your KNOWLEDGE seeking question about a current event?

And it's been proven that drunk people are incapable of safe social distancing. Americans could learn all about Covid from us Brits, so far over 100,000 Brits have died of Covid.  Wear a face mask that covers both nose and mouth, avoid everyone, wash your hands and only drink alcohol with the people you share a house with.

People should obey the rules and do their part.
