They had bands like that at a wedding I did in August.
Go figure, almost NOBODY wore them! I only saw a few masked up older folks who took the yellow ones which meant "conversation is fine, but stay 6 feet away". They had 3 different colors, and noone wore the other ones, lol.
That's a pretty interesting poll result when you consider the way the media portrays the public's level of fear and terror.
While we expect like minded folks in a given family - there are of course two families, and a number of out-liars in the form of friends and neighbors.
