Unavoidably slightly political but...

I saw a shift in behavior following Trump's conference appointing Mike Pence as the effective coronavirus czar.

Every morning there was a small stash of N95 masks at my local Home Depot until yesterday. Similarly I started seeing specific sorts of non-perishables disappearing from the shelves of Trader Joe's and Safeways. Where it goes next, I don't know. But I think the crowd has spoken on the subject already.

Off topic from your post but:

Why do you go to Home Depot every morning?

Likely to buy these masks :D

Correlation, causation, etc.
