My working hypothesis during June and July was that Massachusetts was a lot like a cool room in a warm house - do nothing, and eventually the surroundings would bring the mercury up to the domestic average. I'm not going to run off with this analogy and accuse us of doing nothing, but... well, the case counts are climbing again, so something's cooking.
The local chatter seems focused on blaming certain decisions and activities - we reopened indoor dining too soon, people are stupidly throwing large parties, everyone is sitting bumper to bumper at the beach. I agree that not a single one of those things helped keep the numbers down, but I also know the truth I'm reminded of every day in my apartment - if I leave the door open with my air conditioner running, I might as well not have the thing turned on at all.
