What are Vermont, New Hampshire and Maine doing right on COVID? With almost every other state having been hit hard at some point or another, they've become real outliers relative to the rest of the country.

One starting point might be that they are among the only states in the country that are rural (indeed, *quite* rural based on the more sophisticated density metrics I prefer) but not particularly Republican so maybe more mask-wearing, etc.

Also: small average household size, not very religious (to the extent that church gatherings can serve a vector for spread) and quite "outdoor-oriented", although that could start to be a problem with colder weather.
