New York got hit hard and ended up in a 3 month lock down.
They came up with a re-open plan and reached the target June 7, the following day phase 1 of 4 was started.
Clearly they are still very nervous of this pandemic (after first hand experience) but they have a published plan based on a number of things some are cases per day and number of hospital & ICU beds available, all pretty sensible stuff.

Interesting they have border restrictions via a formula also a less than 24 hour exclusion.
