We are not out of the woods, and it is quite possible we may find ourselves back home this fall working from home and still trying to get a handle on Covid 19. Schools might be via internet again through 2021.
Yes, we in New England are a hearty breed for sure and we currently are the healthiest in the United States. Well we will be until Texans and Floridians migrate to Maine to seek refuge from the heat. By doing so , they will probably ignore the 14 day quarantines, masks, and re-infect us all. I'm not really an alarmist, but if you are not wearing a mask when anywhere in Salem or New England then you are not doing yourself, your family or anyone you know any favors.
Don't trust Folks from Texas, Florida, Arizona etc to do the right thing. Control what you can to keep yourself and your families safe, continue the course and wear a mask.
