Large gatherings should still follow social distance guidelines, even when outside. If people are going to be nut to butt outside, that is not a good idea.
@The Dude why is that an interesting take? It's pretty much the guidance from the health officials and local governments where COVID has been hit hardest.
Regarding the "nut to butt" comment. It's just my favorite phrase to use when talking about crowded situations. If you've been to O Street on a Friday or Saturday night, or trying to walk into the North stadium at Memorial Stadium, it's an applicable phrase.
