Been biking the past 2 evenings in Baltimore City (South Baltimore to be specific). Maybe 20% are wearing masks. Even saw like 2 people biking with masks on. Some joggers wearing masks (actual people jogging, not the other kind of "jogger"), and some people walking with masks on. And this was in an area with lots of walkers. What was interesting is how places had plastic jersey walls closing of parts of the streets so that restaurants could put tables there. Places were mostly either closed or open and had a lot of people in them. I did not see the cruise ships docked in the port.
"Thank you for not wearing a mask!"
Conversely, if you have the guts, ask people wearing a mask two questions:
1. "Why are you wearing a mask?" They will reply with some false answer about safety.
2. "How many outdoor transmissions have there been worldwide?"
And that's enough. No need to get into any argument. Let them look up the answer.
