I can’t imagine the current quarantine order will stand as is. For one thing, Florida has already surpassed CT in cases (as have MA, CA, MI, IL, PA and TX).
NY, NJ and CT were just the first to be hit hard. I think we’re going to see numbers there decrease while numbers grow in other areas. If Florida is going to impose quarantine on travelers from other states, it’s going to be a constantly moving target.
And while I would like to think people will be honest, no one is going to track every traveler who enters FL, especially those who drive in.
