Not a bubble is what my stupid neighbors just did - party at one house with 15 adults and assorted kids, then days later visiting, with some of those same kids, another house not at the party. That’s how people get sick.
So it’s not going to work for the stupid. But for thinking adults, it answers the problem of lack of social contact at the same time making contact tracing pretty easy.
And, most important, if one of the bubble friends gets sick, the others know immediately and can start preliminary treatment, possibly heading off more serious illness. Remembering our early cases were people who waited until they were on death’s doorstep before they sought treatment, with notsogood outcomes because of the time delay.
This morning, there is a group of about 30 jet skis and a couple of boats zipping up and down. All packed with as many people as can fit. I’ve never seen such a huge group. Probably a family reunion. Bet some will get sick. They’ll leave their rental infected and in turn housekeeping, our grocery store, convenience stores, gas stations, the jet ski rental, our restaurants, etc. all infected.
