I agree about the euphoria, and I also think there are states that are not providing the needed oversight. I am curious about one thing: are these venues you mention union productions?
I expect that what we will continue to see in New York is a hard push on vaccinations, and also effective vaccine/testing requirements in venues. I'd also note that every death is a tragedy, but they are a trailing statistic. Yesterday there were 22 deaths in NY state. The acceptable number is zero.
