I can't speak for the officials of the city of Boston or the commonwealth of Massachusetts. Vaccinations in that area are high and new cases of covid are low, so I can understand why someone who's young, healthy, and vaccinated would go, but I certainly would not. Looking at the map, I wouldn't go to anything indoors in Florida, SC, TEN, GA, AL, MS, LA TX, KY, WV, IN, or WY. Where I live, the stores are all asking people to wear masks.
