I 100% agree with the sentiment of your post. Apr 30 seems a little arbitrary to me, but you def can’t keep everything shut down indefinitely. Where that line is, I don’t know.
I tend to err more on the side of caution so we don’t have a horrible second wave of cases/deaths, but as you said, maybe there are other ways to mitigate that. I’d hope that there’s a government agency that’s been modeling that already, but who knows.
