there s not as big of a crowd as we have seen last night. the events are getting started here. big or small, the dogs bob and weave through the crowd. they can pick up the scent of covid from sweat on your feet. if they detect the scent, they will sit. that s when they will come and tell the person attending this event that they need to go to another tent not far from here and take a rapid covid-19 test. we are in this space where we are trusting people. if you are at an event, a large one like this without a mask, that you have been fully vaccinated. but experts like john and other folks we talked to have spent the last year training the dogs, they say the dogs could act as the safety net between trusting each other, but not having a vaccine passport. if you are worried are you vaccinated, a dog like this can give us an extra buffer to make us feel safer.
