We actually did that in Pa. throughout the entire covid. Most of the state's land are rural counties, and initially the hard early lock down was just the large urban areas. Finally they added every county after a few weeks. On reopening they've had three stages. Most of the rural counties went from red status to yellow status first, then they added the west and central state urban areas to yellow next. The eastern area around Philly was the last opened since they had suffered mostly due to their early proximity to New York City/New Jersey. Finally, they went to the green stage, again by individual county level. The initial red stage was one of the strictest in the country with only a few very essential businesses open. The numbers were coming down fine until tourist season imported it back into the state. And then those that brought it back hit the nightclub bars, and super spread. It's leveled off now though. Keep the nightclub type bars shut down and it can work. Mostly dealing with the really 'big' problem of results coming back so late (some more than four weeks old) that they don't really give a true picture of actual present day numbers, or even present infection rate. Numbers are all skewed with the date batch mix ups, and it hurts the contact tracing program immensely. ......The Miami area has their own unique challenges. That would take pages to enumerate. But, bottom line, they are paying the price for being the playground of the nation's rich and famous, plus all the legitimate money and drug money that runs the society. I don't think anyone can tell those people what to do, mayor or governor.
