This week's game changer is the beginning of vaccine requirements for indoor life in NYC. The Mayor's new "Key to NYC" program began yesterday, although enforcement is still a month off. For vaccinated tourists it will increase a sense of safety and it won't stop families from coming—under 12s are still welcome, just required to be masked and accompanied by a vaccinated adult. For the unvaccinated, the indoor city will become less accessible, although so much is now outdoors that they should still be able to drink, dine, and otherwise get around.
